Challenge 2: Updating Outer Scope Values

Let’s look at another coding challenge.

Problem Statement

You must implement the update_var() function that takes in a value as parameter, and updates the value of the var variable in the outer scope to the one supplied as a parameter. Return the updated var at the end. If var doesn’t exist in the outer scope, your function should create it.

Sample input #1

var = 5

print(update_var(7))

Sample output #1

7

Sample input #2

# Assuming var doesn't exist
# var = 5

print(update_var(8))

Sample output #2

8
