Introduction

Converting a string to uppercase is a common task in programming, especially when you want to standardize text data. This tutorial will guide you through creating a Python program that converts a given string to uppercase.

Example:

• Input: hello world

• Output: HELLO WORLD

• Input: Python Programming

• Output: PYTHON PROGRAMMING

Problem Statement

Create a Python program that:

• Takes a string as input.
• Converts the string to uppercase.
• Displays the uppercase string.

Solution Steps

1. Take Input from the User: Use the input() function to get a string from the user.
2. Convert the String to Uppercase: Use the upper() method to convert the string to uppercase.
3. Display the Uppercase String: Use the print() function to display the converted string.

Python Program

# Python Program to Convert String to Uppercase
# Author: https://www.rameshfadatare.com/

# Step 1: Take input from the user
input_string = input("Enter a string: ")

# Step 2: Convert the string to uppercase
uppercase_string = input_string.upper()

# Step 3: Display the uppercase string
print(f"The uppercase string is: {uppercase_string}")

Explanation

Step 1: Take Input from the User

• The input() function prompts the user to enter a string. The input is stored in the variable input_string.

Step 2: Convert the String to Uppercase

• The upper() method is used to convert the entire string to uppercase. This method does not modify the original string but returns a new string with all characters converted to uppercase.

Step 3: Display the Uppercase String

• The print() function is used to display the converted uppercase string.

Output Example

Example 1:

Enter a string: hello world
The uppercase string is: HELLO WORLD

Example 2:

Enter a string: Python Programming
The uppercase string is: PYTHON PROGRAMMING

Example 3:

Enter a string: OpenAI
The uppercase string is: OPENAI

Conclusion

This Python program demonstrates how to convert a string to uppercase using the upper() method. It’s a simple and efficient way to standardize text data, ensuring that all characters in the string are in uppercase. This example is useful for beginners to understand basic string manipulation in Python.
