Description

DataFrame.describe in Python takes a vararg, i.e. it can be invoked this way:

df.describe('col1', 'col2', 'col3')

Most of our DataFrame functions accept a list in addition to varargs. describe should do the same, i.e. it should also accept a Python list:

df.describe(['col1', 'col2', 'col3'])
