They call storage objects "variables" because the value in them can (and generally will) be changed by the program. What you see on the top line is an assignment, not a definition.

And you can always assign a different value to a variable regardless of whether it was given a value already.

Exactly as Steven has said. Here is an example:
a = None # here a equals None
b = 2 # here b equals 2
a = b # here a is now assigned the value of b where b equals 2, therefore a equals 2 as well

I understand what you explained no problem. But I supposed question did not include the original challenge request. I don't understand what they are asking for.

  1. The variable name age is not created yet and I think i'm not supposed to create it.
  2. We are not using the THEN statement yet. So that I may answer ====if age >=13: THEN admitted = True====

So how would you go about answering the challenge?

I'm going to create a variable named age.

I need you to make an if condition that sets admitted to True if age is 13 or more.

You're quite right. You don't create the variable named "age", you just test it.

There's no "THEN" statement in Python. The code controlled by the "if" statement will follow it and be indented further to the right.

So with correct indentation, and leaving out the word "THEN", your answer should work.

No the answer still did not work. I am not understanding this challenge at all. I've look at the video several times and the notes. Not sure how I am supposed to deduct the answer from that.

So if I just format the answer you gave in item (2) and remove the word "THEN" from it:

admitted = None
if age >= 13:
    admitted = True

Is this your task 1 answer? And it doesn't pass?

Gosh I cannot believe it. I just wanna hit this site on the testicles right now. The question/answer/tips are SO vague. I don't think I would have been able to answer this if not for Steve Parker. I did not realize that I had to CHANGE admitted = True. I thought the 'if' statement would do the work like when working with the {}.
