What are common scope errors in Python?

Common scope errors in Python include issues like using variables before they are defined, or misunderstanding local vs global scope.

Can you give me an example of a local vs global variable?

Sure! A global variable is defined outside of any function, while a local variable is defined within a function. For example:

x = 10  # global variable

def my_function():
    y = 5  # local variable
    print(x + y)

my_function()  # This will print 15
print(y)  # This will raise an error because y is not defined outside the function.

What happens if I try to access a local variable outside its function?

If you try to access a local variable outside its function, you'll get a NameError because the variable is not defined in that scope.

How can I avoid scope errors in my code?

To avoid scope errors, always declare your variables in the appropriate scope, and use the global keyword if you need to modify a global variable inside a function.
