Why won't the assignment in else block be done?

I have written a simple if-else condition for the challenge task, but it keeps returning the same error: "Bummer! 'admitted' is not False. I tried the exact same code in the console and it works fine. Please help me complete the challenge.

conditions.py 
admitted = None
if age >= 13:
  admitted = 'True'
else:
  admitted = 'False'

False and True are key words in Python. They should not be quoted unless you wish to create strings. So when it says admitted is not False it means it is not equal to the built in value. Remove the quotes.

Wow! Thank you Chris. Got it done!! One doubt though. I get that the challenge wouldn't complete because 'admitted' couldn't be assigned False because of the quotes. But how did it work for True? Because that was the first task of the challenge, to assign 'admitted' the value of True and it worked with the quotes.

The grader runs your code with various values for age to test the branches in the code flow.

When testing for True the grader may use the "truthiness" of admitted. When set to a string, admitted is "truthy".
