Get list from pandas DataFrame column headers?

Question

I want to get a list of the column headers from a pandas DataFrame. The DataFrame will come from user input so I won't know how many columns there will be or what they will be called.For example, if I'm given a DataFrame like this: >>> my_dataframe y gdp cap 0 1 2 5 1 2 3 9 2 8 7 2 3 3 4 7 4 6 7 7 5 4 8 3 6 8 2 8 7 9 9 10 8 6 6 4 9 10 10 7I would like to get a list like the one below: >>> header_list [y, gdp, cap]

Answer 1

If you have a pandas DataFrame named df, you can get the column headers by

>> df.columns

This return a pandas Index object.

If you want to save it as a Python list to header_list:

>> header_list = list(df.columns)
