How to remove multiple columns that end with same text in Pandas?

Question

I\'m trying to remove a group of columns from a dataset. All of the variables to remove end with the text \"prefix\".

I did manage to \"collect\' them into a group

Answer 1

using filter and regex

df.filter(regex=r'^((?!prefix).)*$')

Demo

df = pd.DataFrame(np.random.rand(2, 6),
                  columns=['oneprefix', 'one',
                           'twoprefix', 'two',
                           'threeprefix', 'three'])

df.filter(regex=r'^((?!prefix).)*$')

where:

df

All are about the same
