The question on the Boolean logic part

Question

I am learning the python Boolean logic part now, but I don’t understand the question of “not” on the test. The question says
What is the output?
If not true:
Print(“1”)
elif not (1 + 1==3):
Print(“2”)
else:
Print(“3”)

I understand that not true is false and not false is true but, I don’t get what the whole question is talking about. What is not true? Isn’t there supposed to be an equation on the top? Or is something wrong with my tab?

Answer 1

A classical "if" statement goes like this:

if (condition):
(what to do if condition is true)

Said condition will always return "True" or "False". So, imagine a program:

if True:
print("1")

As the "True" condition returns... well, True, the program will go ahead and output 1. Now, back to the original question:

if not True:
print("1")

Not True, rather obviously, evaluates to False and hence the first statement is not fulfilled. Next line:

elif not (1 + 1 == 3):
print("2")

As the condition (1 + 1 == 3) returns False, but there is a "not", it returns True instead and 2 is the output.

Hope you learned something from this incredibly lengthy explanation!

Answer 2

every condition returns true or false, so just "true" basically means always yes (or no in this case because of the not)
