# # to get functionality from other modules we should import them
# import random  # provides an ability to use all the functions from that module
# from random import randint
#
# # x=random.randint(1,10)
# # if you need only one method from module you should use the following
#
# x = randint(1, 10)
# # but you can't use shufle()
# l = [1, 2, 3]
# random.shuffle(l)
# print(l)
# print(x)
#
# # it is possible to import with name that you selected
# from random import shuffle as shuffle_my_list
#
# my_l = [2, 3, 4, 5]
# shuffle_my_list(my_l)
# print(my_l)

# import math

# print(math.sqrt(123456789))
