Hands-On Exploratory Data Analysis with Python

Using string functions with a pandas DataFrame

Let's use built-in functions with a pandas DataFrame. We will continue to use the same dataset that was imported in the previous section. Most of the string manipulation functions in Python work with the pandas vectorized string methods.

Here is a list of pandas string functions that reflect Python string methods:

Let's practice the following use cases:

1. Extract the first sentence from the text column of the DataFrame and convert it into lowercase characters, as follows:

 text[0].lower() 

2. Convert all the comments in the text column ...
