Python program to generate a random number. There are two Python language program to produce random number. In the first program there is no range or limit. However, in second program, random variable generated with in given range. This program is useful for beginners, CBSE class 11, 12 and B Tech Computer science with python lab and board exams.
Program 1: Python Program to Generate a Random Number
In Python programming, we can generate a random integer, doubles, longs in various ranges by importing a “random” class.
In the following example, we will learn how to generate random numbers using the random module.
Source code:
import random
n = random.random()
print(n)Click below button to Download Source Code
Source code explanation
- Random library is imported.
- Random function of Random library is called and assigned to a variable n
- The variable n is printed
Output of Program:
Output Explanination
It gives the random variable without any limiting to the value.
Program 2 : Generating a Random variable in a given Range
Python random module provides the randint() method that generates an integer number within a specific range. We can pass the two numbers as arguments that defines the range. Let’s understand the following example.
Source code :
import random
n = random.randint(0, 50)
print(n)- Random library is imported.
- Random function of Random library is called and assigned to a variable n
- The function randint(0,50) is giving what is in between in the range.
- The variable n is printed
Output:
Output Explaination:
The number is between 0 and 50 as assigned by randint(0,50)
Thank you for reading and learning Program to Generate a Random number within a range or not in range . Both of the program have been mentioned with source code and output is also shown. This program is useful for CBSE class 11, 12 and B Tech Computer science with python lab and board exams. Below are the links for more programs.
