In this tutorial, we will learn how to program "How to Capitalize the First Letter of Each Word in a File in Python." The objective is to display the contents of a given text file with the first letter of each word capitalized. This tutorial will guide you step by step through the process of capitalizing the first letter of each word. By the end of this tutorial, you will have a solid understanding of how to implement this task effectively in Python, helping you strengthen your problem-solving abilities and improve your coding skills.

This topic is straightforward and easy to understand. Simply follow the instructions provided, and you will complete it with ease. The program will guide you step by step through the process of capitalizing the first letter of each word. So, let's dive into the coding process!

Getting Started:

First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.

Creating Main Function

This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.

while True:
    print("\n============= Capitalize the First Letter of Each Word in a File =============\n")
 
    fname = input("Enter file name: ")
 
    try:
        with open(fname, 'r') as f:
            print("\nFile content with capitalized words:")
            for line in f:
                print(line.title(), end='')  # avoid double newlines
    except FileNotFoundError:
        print(f"File '{fname}' not found!")
 
    # Ask user if they want to try again
    opt = input("\nDo you want to try again? (yes/no): ").strip().lower()
    if opt == 'no':
        print("Exiting program...")
        break
    elif opt != 'yes':
        print("Invalid choice. Exiting program...")
        break

This program reads a text file and capitalizes the first letter of each word in its content. The user provides the filename, and the program displays the modified text directly. After processing, the user can choose to try another file or exit.

Output:
