import random

print(random.randint(1, 10)) # 7

import random

print(random.randrange(1, 10, 2)) # 3

import random

print(random.choice([11, 22, 33, 44, [55, 66, 77]]))  # 44

import random

print(random.sample([11, 22, 33, 44], 2))  # [44, 22]

import random

lst = [11, 22, 33, 44, 55]
random.shuffle(lst)
print(lst)  # [11, 55, 44, 33, 22]
