# Python3.x Python Random Number Generation
[ Python3 Examples](#)
In Python, you can use the built-in `random` module to generate random numbers.
import random
### random.random()
`random.random()` returns a random floating-point number between 0.0 and 1.0:
## Example
import random
random_number =random.random()
print(random_number)
Executing the above code outputs:
0.7597072251250637
### random.randint(a, b)
`random.randint(a, b)` is used to return an integer between a and b (including a and b).
random.randint(a,b)
The function returns a number N, where N is a number between a and b (a <= N <= b), including a and b.
The following example demonstrates how to generate a random number between 0 and 9:
## Example
# -*- coding: UTF-8 -*-# Filename : test.py# author by : www..com# Generate a random number between 0 and 9# Import the random (random number) module import random print(random.randint(0,9))
Executing the above code outputs:
4
### random.choice(sequence)
`random.choice(sequence)` is used to randomly select an element from a sequence:
## Example
import random
list1 =[1,2,3,4,5]
random_element =random.choice(list1)
print(random_element)
## Example
import random
list1 =[1,2,3,4,5]
random_element =random.choice(list1)
print(random_element)
Executing the above code outputs:
4
### random.shuffle(sequence)
`random.shuffle(sequence)` is used to randomly sort the elements in a sequence:
## Example
import random
list1 = [1, 2, 3, 4, 5]
random.shuffle(list1)
print(list1)
Executing the above code outputs:
[3, 2, 4, 5, 1]
