Making HTTP Requests With Python
The requests library is the de facto standard for making HTTP requests in Python. It abstracts the complexities of making requests behind a beautiful, simple API so that you can focus on interacting with services and consuming data in your application. Throughout this course, you’ll see some of the most useful features that requests has […]
Using PyInstaller to Easily Distribute Python Applications
Are you jealous of Go developers building an executable and easily shipping it to users? Wouldn’t it be great if your users could run your application without installing anything? That is the dream, and PyInstaller is one way to get there in the Python ecosystem. There are countless tutorials on how to set up virtual […]
Introduction to Pandas and Vincent
Get an introduction to Pandas and its two main data structures as well as how to visualize your data using Vincent once you are done munging it with Pandas. Note: This course uses Python 2.7 in its coding examples. [ Improve Your Python With 🐍 Python Tricks 💌 – Get a short & sweet Python […]
New Course: Learn Data Cleaning with Python and Pandas
Data cleaning might not be the reason you got interested in data science, but if you’re going to be a data scientist, no skill is more crucial. Working data scientists spend at least 60% of their time cleaning data, and dirty data is often ranked the single biggest barrier data scientists face at work. That’s […]
How to Learn Python for Data Science In 5 Steps
Why Learn Python For Data Science? Before we explore how to learn Python for data science, we should briefly answer why you should learn Python in the first place. In short, understanding Python is one of the valuable skills needed for a data science career. Though it hasn’t always been, Python is the programming language […]
Quick Tip – Speed up Pandas using Modin
I ran across a neat little library called Modin recently that claims to run pandas faster. The one line sentence that they use to describe the project is: Speed up your Pandas workflows by changing a single line of code Interesting…and important if true. Using modin only requires importing modin instead of pandas and thats […]
The Ultimate List of Data Science Podcasts
Podcasts are a great way to immerse yourself in an industry, especially when it comes to data science. The field moves extremely quickly, and it can be difficult to keep up with all the new developments happening each week! Take advantage of those times in the day when your body is busy, but your mind […]

Probabilistic Programming in Python
Learn about probabilistic programming in this guest post by Osvaldo Martin, a researcher at The National Scientific and Technical Research Council (CONICET). Bayesian Inference Bayesian statistics is conceptually very simple; we have the knowns and the unknowns; we use Bayes’ theorem to condition the latter on the former. If we are lucky, this process will reduce the uncertainty about the unknowns. […]
The Ultimate Guide to Python Type Checking
In this guide, you will get a look into Python type checking. Traditionally, types have been handled by the Python interpreter in a flexible but implicit way. Recent versions of Python allow you to specify explicit type hints that can be used by different tools to help you develop your code more efficiently. In this […]
Quick Tip: Comparing two pandas dataframes and getting the differences
There are times when working with different pandas dataframes that you might need to get the data that is ‘different’ between the two dataframes (i.e.,g Comparing two pandas dataframes and getting the differences). This seems like a straightforward issue, but apparently its still a popular ‘question’ for many people and is my most popular question […]
Python Pandas Groupby Tutorial
In this Pandas group by we are going to learn how to organize Pandas dataframes by groups. More specifically, we are going to learn how to group by one and multiple columns. Furthermore, we are going to learn how calculate some basics summary statistics (e.g., mean, median), convert Pandas groupby to dataframe, calculate the percentage of […]
Explorative Data Analysis with Pandas, SciPy, and Seaborn
In this post we are going to learn to explore data using Python, Pandas, and Seaborn. The data we are going to explore is data from a Wikipedia article. In this post we are actually going to learn how to parse data from a URL, exploring this data by grouping it and data visualization. More […]
