Saving Data to a Text File - Python Programming Exercise

In this exercise, you will develop a Python program to collect multiple sentences from the user (continuing until the user presses Enter without typing anything) and save them into a file named "sentences.txt". This exercise is perfect for practicing file handling, loops, and user input in Python. By implementing this program, you will gain hands-on experience in handling file operations, loops, and user input in Python. This exercise not only reinforces your understanding of file handling but also helps you develop efficient coding practices for managing user interactions.

def collect_sentences():
    """
    Collects multiple sentences from the user and saves them into a file.
    Continues until the user presses Enter without typing anything.
    """
    sentences = []
    
    print("Enter sentences. Press Enter without typing anything to finish.")
    
    while True:
        sentence = input("Enter a sentence: ")
        
        # If the user presses Enter without typing anything, stop collecting sentences
        if not sentence:
            break
        
        # Add the sentence to the list
        sentences.append(sentence)
    
    # Save the sentences to a file
    with open("sentences.txt", "w") as file:
        for sentence in sentences:
            file.write(sentence + "\n")
    
    print(f"\n{len(sentences)} sentences were saved to 'sentences.txt'.")


if __name__ == "__main__":
    collect_sentences()

Output

Enter sentences. Press Enter without typing anything to finish.
Enter a sentence: Hello, this is the first sentence.
Enter a sentence: This is the second sentence.
Enter a sentence: Here's another one.
Enter a sentence: 
3 sentences were saved to 'sentences.txt'.
