Pandas dataframe: drop columns whose name contains a specific string

Pandas dataframe: drop columns whose name contains a specific string

I have a pandas dataframe with the following column names:
Result1, Test1, Result2, Test2, Result3, Test3, etc...
I want to drop all the columns whose name contains the word "Test". The
numbers of such columns is not static but depends on a previous function.
How can I do that?
Thanks!
