Understanding Scoping in Python

[yksingh1097]

Because global spam only brings in global scope variables. Not non local variables.

---

# This is global scope area
spam = "global scope"

def print_spam():
    print(spam)

# soon as you get into a function. It a local variable.
def spam_it():
    def update_spam():
        # grabs  spam from 1 layer down.
        nonlocal spam
        spam = "nonlocal"

    def update_global():
        global spam
        spam = "global scope change"

    print_spam()
    spam = "local"
    print(spam)
    update_spam()
    print(spam)
    update_global()
    print_spam()

spam_it()

Okay. Thanks Windspar for your explanation. I understand now.
