What are some common errors with local variables in Python?

What are some common errors with local variables in Python?

Common errors include referencing a variable before assignment, using the same name as a global variable, and scope issues.

Can you explain what happens if I reference a variable before it's assigned?

If you reference a variable before it's assigned, Python raises a NameError, indicating that the variable is not defined.

What about using the same name for a local and global variable?

Using the same name can lead to confusion. The local variable will shadow the global one, making the global variable inaccessible within that scope.

How can I avoid these errors?

To avoid these errors, always initialize your variables, use unique names for local and global variables, and be mindful of variable scope.
