What are the best practices for variable scope in Python?

In Python, it's important to understand local, global, and nonlocal scopes. Best practices include minimizing the use of global variables, using function parameters for data passing, and keeping variable scopes as narrow as possible.

Can you explain the difference between local and global variables?

Sure! Local variables are defined within a function and can only be accessed inside that function. Global variables, on the other hand, are defined outside any function and can be accessed from anywhere in the code.

What are some common mistakes to avoid with variable scope?

Common mistakes include unintentionally modifying global variables inside functions, not using the global keyword when needed, and creating variables with the same name in different scopes, which can lead to confusion.

How can I manage variable scope in larger projects?

In larger projects, it's best to use classes and modules to encapsulate variables and functions, which helps manage scope and reduces the risk of naming conflicts.
