Saving and Sharing Results
When you want to share your work or keep a record for later, saving your results to a file is a practical skill. In Python, you can write text files using the open(), write(), and close() functions. Writing to a file means you can store summaries, reports, or any information you've generated during your daily tasks, making it easy to review or distribute your findings.

When saving files, always use clear and descriptive names, such as "expenses_summary.txt" or "weekly_report.txt", so you can easily identify their contents later. It's important to handle potential errors, like trying to write to a file that is read-only or on a full disk. Using the with statement is a best practice because it automatically closes the file, even if an error occurs, and helps prevent data loss or file corruption.

2. Why is it important to close a file after writing?
3. Fill in the blanks to write a string to a file.
