Python - Random Module

The random module is a built-in module to generate the pseudo-random variables. It can be used perform some action randomly such as to get a random number, selecting a random elements from a list, shuffle elements randomly, etc. random

Generate Random Floats

The random.random() method returns a random float number between 0.0 to 1.0. The function doesn’t need any arguments. random.random()

import random

print(random.random())

`import random

print(random.random())`Try it

Generate Random Integers

The random.randint() method returns a random integer between the specified integers. random.randint()

import random

print(random.randint(1, 100))
print(random.randint(1, 100))

`import random

print(random.randint(1, 100))
print(random.randint(1, 100))`Try it

Generate Random Numbers within Range

The random.randrange() method returns a randomly selected element from the range created by the start, stop and step arguments. The value of start is 0 by default. Similarly, the value of step is 1 by default. random.randrange()

import  random

print(random.randrange(1, 10))
print(random.randrange(1, 10, 2))
print(random.randrange(0, 101, 10))

`import random

print(random.randrange(1, 10)) print(random.randrange(1, 10, 2)) print(random.randrange(0, 101, 10))`Try it

Select Random Elements

The random.choice() method returns a randomly selected element from a non-empty sequence. An empty sequence as argument raises an IndexError. random.choice()

import random

print(random.choice('computer'))
print(random.choice([12,23,45,67,65,43]))
print(random.choice((12,23,45,67,65,43)))

`import random

print(random.choice(‘computer’))
print(random.choice([12,23,45,67,65,43])) print(random.choice((12,23,45,67,65,43)))`Try it

Shuffle Elements Randomly

The random.shuffle() method randomly reorders the elements in a list. random.shuffle()list

numbers=[12,23,45,67,65,43]

random.shuffle(numbers)
print(numbers)

random.shuffle(numbers)
print(numbers)

`numbers=[12,23,45,67,65,43]

random.shuffle(numbers) print(numbers)

random.shuffle(numbers) print(numbers)`Try it Learn more about the random module in Python docs. random module in Python docs
