What are the best practices for variable scope in programming?

Best practices for variable scope include using local variables whenever possible, minimizing global variables, and clearly defining variable scopes to avoid conflicts.

Can you explain why minimizing global variables is important?

Minimizing global variables helps prevent unintended side effects and makes your code easier to maintain and debug.

What are local variables and how do they differ from global variables?

Local variables are defined within a function and can only be accessed there, while global variables are accessible throughout the entire program.

How can I manage variable scope in large projects?

In large projects, use modules or classes to encapsulate variables, and follow consistent naming conventions to avoid scope conflicts.
