Understanding Basic Type Annotations in Python is like putting a clear label on a box. It helps both you and others know exactly what’s inside, reducing confusion and potential errors. Just like in a well-organized workshop, when tools are labeled, you can grab what you need quickly.
In programming, type annotations offer that same clarity.
They allow us to specify the expected data types of variables, function parameters, and return values, making our code more readable and maintainable.
