In this article, we will use a sample DataFrame as shown in the example code below:

The resulting DataFrame is as shown below:

Feel free to use your dataset for better understanding.

For example, to get the first and second columns (including all rows), we can do the following:

The above should return:

Select Column by Index Range

An example is as shown below:

This should return:

Select Columns Between Column Names

In our example DataFrame, we can do:

This should return a DataFrame as shown:
