Data Analysis with Python and Pandas Tutorial Introduction
 
10:26
Pandas is a Python module, and Python is the programming language that we're going to use. The Pandas module is a high performance, highly efficient, and high level data analysis library. At its core, it is very much like operating a headless version of a spreadsheet, like Excel. Most of the datasets you work with will be what are called dataframes. You may be familiar with this term already, it is used across other languages, but, if not, a dataframe is most often just like a spreadsheet. Columns and rows, that's all there is to it! From here, we can utilize Pandas to perform operations on our data sets at lightning speeds.

Pandas for Data Analysis | SciPy 2017 Tutorial | Daniel Chen
 
03:45:17
There are audio issues with this video that cannot be fixed. We recommend listening to the tutorial without headphones to minimize the buzzing sound. Tutorial information may be found at https://scipy2017.scipy.org/ehome/220975/493423/ Data Science and Machine learning have been synonymous with languages like Python. Libraries like numpy and Pandas have become the de facto standard when working with data. The DataFrame object provided by Pandas gives us the ability to work with heterogeneous unstructured data that is commonly used in "real world" data. New learners are often drawn to Python and Pandas because of all the different and exciting types of models and insights the language can do and provide, but are awestruck when faced with the initial learning curve. This tutorial aims to guide the learner from using spreadsheets to using the Pandas DataFrame. Not only does moving to a programming language allow the user to have a more reproducible workflow, but as datasets get larger, some cannot even be opened in a spreadsheet program. The goal is to have an absolute beginner proficient enough with Pandas that they can start working with data in Python. We will cover how to load and view our data. Then, some basic methods to do quick visualizations of our data for exploratory data analysis. We will then work on combining and working multiple datasets (concatenating and merging), and introduce what Dr. Hadley Wickham has coined "tidy data". Tidy data is an important concept because the process of tidying data will fix a host of data problems that are needed to perform analysis. We then cover functions and applying methods to our data with a focus on data cleaning, and how we can use the concept of split-apply-combine (groupby) to summarize or reduce our data. Finally, we cover the basics of string manipulation and how to use it to clean data before briefly covering the role of Pandas in analysis packages such as scikit learn. The tutorial will with a fitted model. The goal is to get people familiar with Python and Pandas so they can learn and explore many other parts of the Python ecosystem.

PyData Carolinas 2016 This tutorial aims to expose future data analysis with the Python Pandas library. The tutorial is meant for absolute beginners to Pandas and Python as a programming language. We will begin with loading tabular data and various ways to calculate summary statistics and visualize data. Next, we will learn various ways to join multiple datasets, and how we can work with missing values etc. The purpose of the tutorial is to expose users to Pandas for data analysis and move users into a more reproducible analysis workflow compared to spreadsheet programs. The tutorial will begin with loading in tabular data and various ways to view columns and rows of data. The initial part of the tutorial will show users how to load in data and quickly create descriptive statistical plots. Next, we will cover more of pandas internal data structures. This will cover some fundamental knowledge about Python as a programming language, mainly object methods. Finally, before showing users basic data cleaning examples, we will cover data visualizations using matplotlib, seaborn, and pandas itself. The next section of the tutorial will show learners how to assemble and merge multiple datasets, and how to work with missing values. Lastly, before we get to fitting models, I will go over how to recode variables for analysis. The main purpose is to show users how to use Pandas, and not how to fit machine learning models. However, I show a simple model at the end so users see how data cleaning and analysis all fit together in a workflow.

Quentin Caudron - Introduction to data analytics with pandas
 
01:51:34
Description Data analytics in Python benefits from the beautiful API offered by the pandas library. With it, manipulating and analysing data is fast and seamless. In this workshop, we'll take a hands-on approach to performing an exploratory analysis in pandas. We'll begin by importing some real data. Then, we'll clean it, transform it, and analyse it, finishing with some visualisations. Introduction In this hands-on workshop, we'll walk through the exploratory analysis of real-world data. Datasets are often messy, full of holes and inconsistencies, and a data scientist or analyst may spend a large fraction of their time cleaning and preparing data. Fortunately, pandas makes a lot of this fairly trivial. It allows the user to import data from all sorts of different sources, and then manipulate the powerful DataFrame object. Analytics with pandas are human-friendly. Workshop Pulling in the data Starting with some data in CSV form, we'll look at the general properties of our dataset. What columns do we have; what kind of values are contained in them ? We'll identify problematic fields, and join two datasets to make one complete dataframe. Cleaning We've identified problems with our data, and now it's time to correct them. We'll fill in missing values, drop irrelevant rows, and fix incorrect datatypes. Transforming the data Next, we'll standardise some numerical fields where we're looking for deviations rather than absolute values, and derive some new columns based on the data we have. Visualisation Throughout, we'll be generating visualisations, to guide us in where to go next. Prerequisites You'll need to be fairly comfortable working with Python. We won't be doing anything overly complicated, but having a grasp of Python syntax is expected. Laptop If you want to follow along, please have a working Python setup, with pandas and matplotlib installed. Aim for a recent version of pandas. If you're unsure what to install, I recommend getting Python 3 through Anaconda : https://www.continuum.io/downloads - this distribution comes with everything you need and is very friendly. www.pydata.org PyData is an educational program of NumFOCUS, a 501(c)3 non-profit organization in the United States. PyData provides a forum for the international community of users and developers of data analysis tools to share ideas and learn from each other. The global PyData network promotes discussion of best practices, new approaches, and emerging technologies for data management, processing, analytics, and visualization. PyData communities approach data science using many languages, including (but not limited to) Python, Julia, and R. PyData conferences aim to be accessible and community-driven, with novice to advanced level presentations. PyData tutorials and talks bring attendees the latest project features along with cutting-edge use cases.

This is a review of the fantastic Python for Data Analysis. I learnt a lot from this book by Wes McKinney. Its section on IPython is excellent and it explains Numpy extremely well: two chapters are dedicated to Numpy covering the basics and advanced topics. It really helps you to visualize numpy arrays. The Pandas coverage is excellent and you learn what a powerful tool Pandas can be. I always use it for my data analysis, usually in a jupyter notebook and I love what it can do. If you are new to data analysis and are looking for an introductory book to explain how to do it in Python, I haven't seen a better one than this.

Applying Comparison Operators to DataFrame - p.12 Data Analysis with Python and Pandas Tutorial
 
11:55
Welcome to part 12 of the Data Analysis with Python and Pandas tutorial series. In this tutorial, we're goign to talk briefly on the handling of erroneous/outlier data. Just because data is an outlier, it does not mean it is erroneous. A lot of times, an outlier data point can nullify a hypothesis, so the urge to just get rid of it can be high, but this isn't what we're talking about here. What would an erroneous outlier be? An example I like to use is when measuring fluctuations in something like, say, a bridge. As bridges carry weight, they can move a bit. In storms, that can wiggle about a bit, there is some natural movement. As time goes on, and supports weaken, the bridge might move a bit too much, and eventually need to be reinforced. Maybe we have a system in place that constantly measures fluctuations in the bridge's height.

Rolling statistics - p.11 Data Analysis with Python and Pandas Tutorial
 
14:19
Welcome to another data analysis with Python and Pandas tutorial series, where we become real estate moguls. In this tutorial, we're going to be covering the application of various rolling statistics to our data in our dataframes. One of the more popular rolling statistics is the moving average. This takes a moving window of time, and calculates the average or the mean of that time period as the current value. In our case, we have monthly data. So a 10 moving average would be the current value, plus the previous 9 months of data, averaged, and there we would have a 10 moving average of our monthly data. Doing this is Pandas is incredibly fast. Pandas comes with a few pre-made rolling statistical functions, but also has one called a rolling_apply. This allows us to write our own function that accepts window data and apply any bit of logic we want that is reasonable. This means that even if Pandas doesn't officially have a function to handle what you want, they have you covered and allow you to write exactly what you need. Let's start with a basic moving average, or a rolling_mean as Pandas calls it. You can check out all of the Moving/Rolling statistics from Pandas' documentation.

Concatenating and Appending dataframes  - p.5 Data Analysis with Python and Pandas Tutorial
 
07:51
Welcome to Part 5 of our Data Analysis with Python and Pandas tutorial series. In this tutorial, we're going to be covering how to combine dataframes in a variety of ways. In our case with real estate investing, we're hoping to take the 50 dataframes with housing data and then just combine them all into one dataframe. We do this for multiple reasons. First, it is easier and just makes sense to combine these, but also it will result in less memory being used. Every dataframe has a date and value column. This date column is repeated across all the dataframes, but really they should all just share the one, effectively nearly halving our total column count. When combining dataframes, you might have quite a few goals in mind. For example, you may want to "append" to them, where you may be adding to the end, basically adding more rows. Or maybe you want to add more columns, like in our case. There are four major ways of combining dataframes, which we'll begin covering now. The four major ways are: Concatenation, joining, merging, and appending. We'll begin with Concatenation.

Scikit Learn Incorporation - p.16 Data Analysis with Python and Pandas Tutorial
 
10:33
In this Data Analysis with Pandas and Python tutorial series, we're going to show how quickly we can take our Pandas dataset in the dataframe and convert it to, for example, a numpy array, which can then be fed through a variety of other data analysis Python modules. The example that we're going to use here is Scikit-Learn, or SKlearn. In order to do this, you will need to install it: pip install sklearn From here, we're almost already done. For machine learning to take place, at least in the supervised form, we need only a couple things. First, we need "features." In our case, features are things like current HPI, maybe the GDP, and so on. Then you have "labels." Labels are assigned to the feature "sets," where a feature set is the collective GDP, HPI, and so on for any given "label." Our label, in this case, is either a 1 or a 0, where 1 means the HPI increased in the future, and a 0 means it did not.

Adding other economic indicators - p.14 Data Analysis with Python and Pandas Tutorial
 
14:03
Hello everyone and welcome to Part 14 of our Data Analysis with Python and Pandas for Real Estate investing tutorial series. We've come quite a long ways here, and the next, and final, macro step that we want to take here involves looking into economic indicators to see their impact on housing prices, or the HPI. Text based version of this tutorial and sample code: http://pythonprogramming.net/economic-factors-data-analysis-python-pandas-tutorial/ There are two major economic indicators that come to mind out the gate: S&P 500 index (stock market) and GDP (Gross Domestic Product). I suspect the S&P 500 to be more correlated than the GDP, but the GDP is usually a better overall economic indicator, so I may be wrong. Another macro indicator that I suspect might have value here is the unemployment rate. If you're unemployed, you're probably not getting that mortgage. We'll see though. We've been through the process for adding more data points, so I do not see much point in dragging you all through this process. There will be one new thing to note, however. In the HPI_Benchmark() function, we're changing the "United States" column to be US_HPI. This makes a bit more sense when we're bringing in other values now. For GDP, I couldn't find one that encompassed the full time frame. I am sure you can find a dataset, somewhere, with this data, maybe even on Quandl. Sometimes you have to do some digging. I also had trouble finding a nice long-term monthly unemployment rate. I did find an unemployment level, but we really want more of a percentage/rate, otherwise we need to divide the unemployment level by the population. We could do that if we decide unemployment rate is worth having, but we'll work with what we get first. http://pythonprogramming.net https://twitter.com/sentdex

Its design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than possible in languages such as C++ or Java. The language provides constructs intended to enable writing clear programs on both a small and large scale. Python supports multiple programming paradigms, including object-oriented, imperative and functional programming or procedural styles.It also supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed.

Resampling - p.9 Data Analysis with Python and Pandas Tutorial
 
11:51
Welcome to another data analysis with Python and Pandas tutorial. In this tutorial, we're going to be talking about smoothing out data by removing noise. There are two main methods to do this. The most popular method used is what is called resampling, though it might take many other names. This is where we have some data that is sampled at a certain rate. For us, we have the Housing Price Index sampled at a one-month rate, but we could sample the HPI every week, every day, every minute, or more, but we could also resample at every year, every 10 years, and so on. Another environment where resampling almost always occurs is with stock prices, for example. Stock prices are intra-second. What winds up happening though, is usually stock prices are resampled to minute data at the lowest for free data. You can buy access to live data, however. On a long-term scale, usually the data will be sampled daily, or even every 3-5 days. This is often done to keep the size of the data being transferred low. For example, over the course of, say, one year, intra-second data is usually in the multiples of gigabytes, and transferring all of that at once is unreasonable and people would be waiting minutes or hours for pages to load. Using our current data, which is currently sampled at once a month, how might we sample it instead to once every 6 months, or 2 years? Try to think about how you might personally write a function that might perform that task, it's a fairly challenging one, but it can be done. That said, it's a fairly computationally inefficient job, but Pandas has our backs and does it very fast.

Kevin Markham - Using pandas for Better (and Worse) Data Science - PyCon 2018
 
03:20:43
Speaker: Kevin Markham The pandas library is a powerful tool for multiple phases of the data science workflow, including data cleaning, visualization, and exploratory data analysis. However, proper data science requires careful coding, and pandas will not stop you from creating misleading plots, drawing incorrect conclusions, ignoring relevant data, including misleading data, or executing incorrect calculations. In this tutorial, you'll perform a variety of data science tasks on a handful of real-world datasets using pandas. With each task, you'll learn how to avoid either a pandas pitfall or a data science pitfall. By the end of the tutorial, you'll be more confident that you're using pandas for good rather than evil! Participants should have a working knowledge of pandas and an interest in data science, but are not required to have any experience with the data science workflow. Datasets will be provided by the instructor. Slides can be found at: https://speakerdeck.com/pycon2018 and https://github.com/PyCon/2018-slides
