Hello, I'm Aya Bouchiha, today, I'm going to share with you 5 useful & helpful methods from a random module.
Firstly, we need to know that the Random module is built-in in python for helping you to create random numbers.
random()
random(): returns a random float n where 0 <= n < 1
import random
print(random.random()) # 0.7291047713945417
randint()
randint(a, b): returns a random integer between the given range. a <= n <= b
import random
print(random.randint(1, 10)) # 7
print(random.randint(-12, 2)) # -10
uniform()
uniform(a, b): returns a random float between the given range. a <= n <= b
import random
print(random.uniform(5.7, 12)) # 10.096664083501162
print(random.uniform(10, 100.2)) # 95.00994365426938
shuffle()
shuffle(sequence, func = random.random): this method shuffle the giving sequence.In addition, It updates the giving sequence and does not return a new one.
import random
users = ['aya', 'simon', 'john']
random.shuffle(users)
print(users) # ['john', 'aya', 'simon']
choice()
choice(sequence): returns a random element from the giving sequence.
import random
users = ['aya', 'john', 'simon', 'kyle']
winner = random.choice(users)
print(winner) # aya :)
Summary
-
random(): returns a random float n where
0 <= n < 1. -
randint(a, b): returns a random integer between the given range.
a <= n <= b. -
uniform(a, b): returns a random float between the given range.
a <= n <= b. - shuffle(sequence, func = random.random): this method shuffle the giving sequence.
- choice(sequence): returns a random element from the giving sequence.
