Python that solves the following:

#B). Create a list of integers, strings, i.e. someList = [3, ' S', 'B', 21] Separate the list into one of only strings, and one of only integers

#C). Compare and contrast the data structure from the official Python list of data structures (i.e. tuples, dicts, lists), i.e. Tuples are the ONLY immutable data structure (there are lists, tuples, sets, dictionaries)

#D). Compare and contrast some Python specialized data types/objects (please select at least a minimum of 2 items, i.e. datetime, collections)
