How do I expand the output display to see more columns of a Pandas DataFrame?

You can expand the output display of a Pandas DataFrame by setting the option 'display.max_columns' in pandas. This can be done by running the following code:

pd.set_option('display.max_columns', None)

This will display all columns in the DataFrame. If you want to display a specific number of columns, you can replace "None" with the number of columns you want to display.

Another way to achieve this is by using the 'head' function to display the first n rows of a dataframe.

df.head(n)

Where n is the number of rows you want to display.
