TextToHTML with File Integration - Python Programming Exercise

In this exercise, you will develop a Python program to enhance the TextToHTML class by adding the ability to save its results into a text file. This exercise is perfect for practicing class definition, method implementation, and file handling in Python. By implementing this class, you will gain hands-on experience in handling class definitions, method implementation, and file handling in Python. This exercise not only reinforces your understanding of object-oriented programming but also helps you develop efficient coding practices for managing user interactions.

Exercise

Texttohtml With File Integration

Objective

Develop a Python program to enhance the TextToHTML class by adding the ability to save its results into a text file. Include a method named save_to_file, which will take the file name as an argument and write the generated HTML content to it.

Tip: Use a file writing mechanism like open() with the mode set to "w" to handle the file operations.
