Python Program to Generate a Random Number

Introduction

Generating random numbers is a common requirement in many programming tasks, such as simulations, games, and security applications. This tutorial will guide you through creating a Python program that generates a random number within a specified range.

Problem Statement

Create a Python program that:

• Generates a random number within a specified range.
• Displays the generated random number.

Example:

• Input: lower_bound = 1, upper_bound = 100
• Output: Generated random number: 42

Solution Steps

1. Import the random Module: Use Python’s built-in random module to generate random numbers.
2. Specify the Range: Define the lower and upper bounds for the random number generation.
3. Generate the Random Number: Use the random.randint() function to generate a random number within the specified range.
4. Display the Result: Use the print() function to display the generated random number.

Python Program

# Python Program to Generate a Random Number
# Author: https://www.rameshfadatare.com/

import random

# Step 1: Specify the range for the random number
lower_bound = int(input("Enter the lower bound: "))
upper_bound = int(input("Enter the upper bound: "))

# Step 2: Generate the random number within the specified range
random_number = random.randint(lower_bound, upper_bound)

# Step 3: Display the result
print(f"Generated random number: {random_number}")

Explanation

Step 1: Specify the Range for the Random Number

• The user is prompted to enter the lower and upper bounds for the random number generation. These inputs are converted to integers using int().

Step 2: Generate the Random Number

• The random.randint() function from Python’s random module is used to generate a random integer within the specified range, inclusive of both bounds.

Step 3: Display the Result

• The print() function is used to display the generated random number. The f-string format is used to include the random number directly within the output string.

Output Example

Example:

Enter the lower bound: 1
Enter the upper bound: 100
Generated random number: 42

Example:

Enter the lower bound: 10
Enter the upper bound: 50
Generated random number: 37

Conclusion

This Python program demonstrates how to generate a random number within a specified range using Python’s random module. It’s a practical example for beginners to understand random number generation and user input handling in Python.
