Can you explain the scope of variables in Python lambda functions?

Sure! In Python, lambda functions have access to variables in their enclosing scope, but they do not create a new scope.

What happens if I try to use a variable that is defined inside the lambda?

If you try to use a variable defined inside the lambda, it will result in a NameError because that variable is not in the enclosing scope.

Of course! Here's an example: x = 10; my_lambda = lambda y: x + y; print(my_lambda(5)) will output 15.

Global variables can be accessed in a lambda function, but you need to declare them as global if you want to modify them.
