How do I access a variable inside a nested function from another function?

Issue

Let’s say I have a code snippet like this :

def z():
    def y():
        v = 10
def x():

and inside function x I want to access variable v. How do I do that in simplest way possible?

Here’s a complicated approach but kinda works. I wouldn’t recommend using this in actual code though.

def z():
    def y():
        y.v = 20
    y.v = 10
    return y

def x():
    y = z()

    print(y.v)
    # 10
    y()
    print(y.v)
    # 20

x()
