Ah, excellent question! You're clearly trying to understand all the boolean operators fully.
The not operator is the simplest of the three boolean operators (and, or, not). Its purpose is to reverse the boolean value of an expression.
- If an expression is
True,notmakes itFalse. - If an expression is
False,notmakes itTrue.
Let's look at the example from your step:
a = True
# ...
print(not a) # The opposite of a
Since a is True, not a will evaluate to False.
If we had:
b = False
print(not b)
This would output True, because not False is True.
So, in essence, not just flips the boolean value to its opposite. It's often used to check if something is not the case.
Do you have any other questions about not or want to see it in a different context?
