Get list from pandas DataFrame column headers

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 7


I would want to get a list like this:

>>> header_list
[y, gdp, cap]

Answer

You can get the values as a list by doing:

list(my_dataframe.columns.values)
