Python Program to Generate a Random Number

In this tutorial, you will learn to generate a random number using inbuild Python random module.

Generating a Random Number

In this example random function returns a random floating value

1import random  
2n = random.random()
3print(n)

Output:

10.4352688540524874

Generating a Number within a Given Range

To get integer value instead of float we can use randint function to generate values between a range.

1import random  
2n = random.randint(0,100) 
3print(n)  

Output:

131

Using random.sample()

The random module also have the sample() method, which generates a list of random numbers.

1import random  
2# Generate 10 random numbers between 0 and 100
3random__sample_list = random.sample(range(0, 100), 10)  
4print(random__sample_list)

Output:

1[89, 8, 42, 90, 80, 1, 86, 28, 3, 6]

Generating a List of numbers Using For Loop

1import random  
2random_list = []  
3for i in range(0,10):  
4    n = random.randint(1,100)  
5    random_list.append(n)  
6print("random_list:", random_list)  

Output:

1random_list: [63, 4, 17, 66, 53, 74, 13, 9, 97, 29]
