Kevin Jacobs has a tutorial on Python’s Pandas library:
There are a few things worth mentioning. Often, Pandas is abbreviated as pd (like Numpy which is often abbreviated as np). If you look at other code, you will see that DataFrames are often abbreviated by df. Here, the DataFrame is constructed using data from a list of lists. The columns argument specifies the keys of the data.
This is a high-level intro, but helps you get your feet wet if you’ve not played with the library.
