# ===================== SUMMARY OF random MODULE =====================
# random module is used to generate random numbers and pick random items.
# random.random() gives float between 0 and 1.
# randint(), randrange(), uniform() generate random numbers in ranges.
# choice(), choices(), sample() select random values from a sequence.
# shuffle() changes the order of a list randomly.
# seed() is used to get the same random output every time for practice.
