What is variable shadowing in Python?

Can you explain what variable shadowing is in Python?

Sure! Variable shadowing occurs when a variable in a local scope has the same name as a variable in an outer scope.

Can you give me an example of variable shadowing?

Of course! If you have a global variable x = 10 and a function where you define x = 5, the function's x shadows the global x.

What happens if I try to access the global variable inside the function?

If you try to access x inside the function, it will refer to the local x, which is 5, not the global 10.

Are there any best practices to avoid variable shadowing?

Yes, it's best to use unique variable names in different scopes or use prefixes to distinguish them.
