What are some common scope issues in Python?

Common scope issues in Python include variable shadowing, the use of global variables, and the LEGB rule. Would you like to know more about any specific issue?

Can you explain the LEGB rule?

Sure! The LEGB rule stands for Local, Enclosing, Global, and Built-in. It describes the order in which Python looks for variables. Local refers to variables defined within a function, Enclosing refers to variables in enclosing functions, Global refers to variables defined at the top level of a module, and Built-in refers to names preassigned in the built-in scope.

What is variable shadowing?

Variable shadowing occurs when a variable in a local scope has the same name as a variable in an outer scope. This can lead to confusion, as the local variable 'shadows' the outer variable.

How can I avoid scope issues in my code?

To avoid scope issues, use clear and descriptive variable names, limit the use of global variables, and be mindful of nested functions. It's also helpful to follow best practices for code organization.
