Data School has a great video on the pandas library. In it, you’ll use pandas to answer questions about a real-world dataset. Through each exercise, you’ll learn important data science skills as well as “best practices” for using pandas. By the end of the tutorial, you’ll be more fluent at using pandas to correctly and efficiently answer your own data science questions.

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 session from PyCon Cleveland 2018, you’ll perform a variety of data science tasks on a handful of real-world datasets using pandas.
