How to generate a random number between 0 and 1 in Python ?

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, 10**5)/ 10**5)

Output:

0.59882

Generate a Random Number between 0 and 1

The Task is to generate a random number between 0 and 1. It is obvious that the number between 0 and 1 will be a floating point number. To generate a random number between 0 and 1, we will make use of the rand() function. The rand() function creates a random number. Approach: Generating a Random Num

Program to generate a random number between L to R

Write a program that generates a random number within a specified range [L, R]. The program should take two integers, L and R, as input and output a random number between L and R (inclusive). Examples: Input: L = 10, R = 20Output: 15 Input: L = -5, R = 5Output: 3 Approach: To solve the problem, foll

How to Generate Random Numbers in R

Random number generation is a process of creating a sequence of numbers that don't follow any predictable pattern. They are widely used in simulations, cryptography and statistical modeling. R Programming Language contains various functions to generate random numbers from different distributions lik

How to generate random numbers from a log-normal distribution in Python ?

A continuous probability distribution of a random variable whose logarithm is usually distributed is known as a log-normal (or lognormal) distribution in probability theory. A variable x is said to follow a log-normal distribution if and only if the log(x) follows a normal distribution. The PDF is d

How to generate a random phone number using Python?

In this article, we will learn how to generate a random phone number using Python. In general, Indian phone numbers are of 10 digits and start with 9, 8, 7, or 6. Approach: We will use the random library to generate random numbers.The number should contain 10 digits.The first digit should start with
