Supercharge Your Python Debugging with f-String Self-Documenting Expressions

We've all written quick print statements like print(f'user_id: {user_id}') to debug our code. Python 3.8 introduced a brilliant shorthand that makes this much faster: just add an equals sign = inside the curly braces.

Writing print(f'{user_id=}') will automatically output both the variable name and its value, formatted as user_id=123. It even preserves whitespace and works with expressions, like f'{user.get_name()=}'. It's a tiny syntax trick that saves thousands of keystrokes over a project's lifetime.
