You just learned three ways to comment in Python: single-line #, multi-line "block" comments, and docstrings.
Now put them to work in a real script. Below is a working Python program that greets a user and calculates their age in months. Your job is to document it with comments — and then run it to see the output.
Your tasks
1. At the very top of the file, add a docstring (triple-quoted string) that says: Greet a user and show their age in months.
2. Above the name = ... line, add a single-line comment: # User details
3. Above the age_in_months = ... line, add a single-line comment: # Convert age from years to months
4. Run the program (no changes to the existing print lines).
Expected output
Hello, Alex!
You are 336 months old.
Constraints
- The docstring must be the very first line of the file
- Use
# for the inline comments (not multi-line strings)
- Do not change the existing code — only add comments
- No external libraries
