Can I use other f-string features?

Yes, you can use several features with f-strings in Python! Here are some common ones:

1. Expressions: You can include expressions inside the curly braces.

   books = 5
   print(f"I have {books * 2} books in total.")
   

2. Formatting Numbers: You can format numbers directly within the f-string.

   price = 19.99
   print(f"The price is ${price:.2f}.")  # Outputs: The price is $19.99.
   

3. Calling Functions: You can call functions inside the curly braces.

   def get_book_count():
       return 5
   print(f"I have {get_book_count()} books.")
   

4. Using Dictionaries: You can access dictionary values.

   book_info = {'title': '1984', 'author': 'Orwell'}
   print(f"'{book_info['title']}' is written by {book_info['author']}.")
   

5. Conditional Expressions: You can use conditional expressions.

   books = 5
   print(f"You {'have' if books > 0 else 'do not have'} books.")
   

These features make f-strings very powerful for creating dynamic and formatted strings. Feel free to explore these in your coding practice!
