Answer to Question #235717 in Python for Anaya Farhan

Question

Show what happens when a variable defined outside a function has the same name as a local variable inside a function. Explain what happens to the value of each variable as the program runs.

Answer 1

In fact - nothing will happen. Each variable will live it's own life in it's scope.

Example:

def my_func():
    var = 20  # inner variable
    return var

var = 10  # outer variable
print(var)
print(my_func())
print(var)

Output:
10
20
10

Any change of inner variable var will not affect outer variable var and vice versa.
