How to Generate a Random Value Between 0 and 1 in Python

1. Generate a Random Value Between 0 and 1 With the random.randint() Function in Python
2. Generate a Random Value Between 0 and 1 With the random.random() Function in Python
3. Generate a Random Value Between 0 and 1 With the random.uniform() Function in Python

This tutorial will introduce methods to generate a random value between 0 and 1 in Python.

Generate a Random Value Between 0 and 1 With the random.randint() Function in Python

The random module provides many methods to generate random numbers in Python. The random.randint(x, y) function generates a random integer between x and y. The following code example shows us how we can generate a random integer between 0 and 1 with the random.randint() function in Python.

import random

for i in range(10):
    print(random.randint(0, 1))

Output:

0
1
1
0
1
1
1
0
0
0

In the above code, we generate random integer values between 0 and 1 with the random.randint() function in Python. This method is technically random, But it gives 0 output most of the time.

Generate a Random Value Between 0 and 1 With the random.random() Function in Python

The random module provides another method for generating a random number called the random.random() function. The random.random() function is used to generate random float values between 0 and 1. The following code example shows us how we can generate a random float value between 0 and 1 with the random.random() function in Python.

import random

for i in range(10):
    print(random.random())

Output:

0.825015043001995
0.9094437659082791
0.33868291714283916
0.5351032318837877
0.15110006300577983
0.35633216995962613
0.6230723865215685
0.35906777048890404
0.48989704057931327
0.5862369192498884

In the above code, we generate random float values between 0 and 1 with the random.random() function in Python. As we can see, there is no repetition in the output.

Generate a Random Value Between 0 and 1 With the random.uniform() Function in Python

Another method provided by the random module to generate random float values is the random.uniform() function. The random.uniform(x, y) function generates random float values between x and y. The following code example shows us how we can generate a random float value between 0 and 1 with the random.uniform() function in Python.

import random

for i in range(10):
    print(random.uniform(0, 1))

Output:

0.013945221722152179
0.5017124648286838
0.877814513722702
0.2272981359909486
0.1752587757552797
0.8360499141768403
0.186039641814587
0.4962755696082156
0.5530128798215038
0.06186876002931674

In the above code, we generate random float values between 0 and 1 with the random.uniform() function in Python.
