Can't Understand a Part?

Question

I am new and currently at Pythan Boolean-Logic part.
In this code:
if not True:
print("1")
elif not (1 + 1 == 3):
print("2")
else:
print("3")

I cannot understand what this part does:
if not True:
print("1")

Please Explain this part??

Answer 1

not True means False.
if False:
print("1")
#This never runs because the condition is False so we jump to the elif part
elif not (1+1==3):
print("2")
1+1==3 is False and not False is True. That's why 2 is printed out.

Answer 2

not True means false. Can you share your full code?

Answer 3

It is same than in speech:
not True ---> False
not False ---> True

Because boolean can only have 2 different values knowing whether a boolean is not true or false would mean that the boolean must be the another possible value.

In speech this would not work for other types of values, a number not 10, could be 5, 4 or any but not 10.
