What are the differences between annotations and docstrings in Python?
Annotations are used to provide hints about the types of variables, while docstrings are used to describe the purpose of functions or classes.
Can you give me an example of each?
Sure! An annotation example: def add(x: int, y: int) -> int:
. A docstring example: def add(x, y): """Adds two numbers."""
.
Are annotations mandatory in Python?
No, annotations are optional in Python. You can write functions without them.
How about docstrings? Are they mandatory?
Docstrings are also optional, but it's a good practice to include them for better code documentation.
