What are the best practices for variable scopes in Python?

In Python, it's important to understand the different scopes: local, enclosing, global, and built-in. Best practices include using local variables whenever possible to avoid unintended side effects.

Can you explain the difference between local and global variables?

Sure! Local variables are defined within a function and can only be accessed there, while global variables are defined outside any function and can be accessed throughout the entire module.

When should I use global variables?

Global variables should be used sparingly. They can be useful for constants or configuration settings, but overusing them can lead to code that is hard to debug and maintain.

What about variable shadowing?

Variable shadowing occurs when a local variable has the same name as a global variable. This can lead to confusion, so it's best to avoid naming conflicts.

Any tips for managing variable scopes in larger projects?

Yes! Use clear naming conventions, limit the use of global variables, and encapsulate functionality within classes or modules to manage scopes effectively.
