Series.str.translate()

table : dict (python 3), str or None (python 2)

In python 3, table is a mapping of Unicode ordinals to Unicode ordinals, strings, or None. Unmapped characters are left untouched. Characters mapped to None are deleted. str.maketrans() is a helper function for making translation tables. In python 2, table is either a string of length 256 or None. If the table argument is None, no translation is applied and the operation simply removes the characters in deletechars. string.maketrans() is a helper function for making translation tables.

deletechars : str, optional (python 2)

A string of characters to delete. This argument is only valid in python 2.
