Add conditionals

The while loop that corrects the offset is a good start, but what if offset is negative? You can try to run the following code where offset is initialized to -6: 

# Initialize offset
offset = -6

# Code the while loop
while offset != 0 :
    print("correcting...")
    offset = offset - 1
    print(offset)

but your session will be disconnected. The while loop will never stop running, because offset will be further decreased on every run. offset != 0 will never become False and the while loop continues forever.

Fix things by putting an if-else statement inside the while loop. If your code is still taking too long to run, you probably made a mistake!

Instructions

  • Inside the while loop, complete the if-else statement:
    • If offset is greater than zero, you should decrease offset by 1.
    • Else, you should increase offset by 1.
  • If you've coded things correctly, hitting Submit Answer should work this time.

If your code is still taking too long to run (or your session is expiring), you probably made a mistake. Check your code and make sure that the statement offset != 0 will eventually evaluate to FALSE!
