How to generate a random number between 0 and 1 in Python ? (original) (raw)

Last Updated : 03 Jan, 2021

The use of randomness is an important part of the configuration and evaluation of modern algorithms.

Here, we will see the various approaches for generating random numbers between 0 ans 1.

Method 1:

Here, we will use uniform() method which returns the random number between the two specified numbers (both included).

Code:

Python3 `

import random

print(random.uniform(0, 1))

`

Output:

0.0023922878433915162

Method 2:

Here, we will use random() method which returns a random floating number between 0 and 1.

Code:

Python3 `

import random

print(random.random())

`

Output:

0.7769332461684861

Method 3:

Here, we will use the numpy to generate the array of the random numbers.

Code:

Python3 `

import numpy as np

x=np.random.random(1)[0] print(x)

`

Output:

0.03394418147881839

Method 4:

Here, we will see the custom approach for generating the random numbers.

randint() is the method which return the random integer between two specified values.

Code:

Python3 `

import random

print(random.randint(0, 105)/ 105)

`

Output:

0.59882
