Answer 3

Also correct is

A = 1
B = 2
if (not (A == B)):
print("A and B are >>not<< equal!")
else:
print("A and B are equal.")

The above syntax is to read more clearly, you need to be aware of closing an opening braces to avoid bracing errors, though, which sometimes may lead in undefined behavior.

Sometimes it just leads to more readable code like above, though, imagine a function/program returning either False/True

def checkIfTrue:
# some code checking something
# ...
return False

Now you can either wrap your lines within a if statement

if (checkIfTrue):
# continue with the program
else:
exit

or just save one indentation level

if (not (checkIfTrue)):
exit
# continue with the program

Answer 4

If you are using C-like programming languages, use ! (Example: !false = true)

Answer 5

Hh

Answer 6

Maine function of not is to reverse the output. If your result is true then not ture will give output false

Answer 9

In python how to use it.?

Answer 10

The not operator is an inverter meaning the condition followed by the operator is inverted
Eg
Print (not True)
This will return false
And since it is used to invert, its an unary operator, i.e it takes only one condition

Answer 11

You can use 'not' in the boolean logic just like '!= True' meaning if the statement is false.

Answer 12

you use not for not intend of the list

Answer 13

I know that A != B
A =1
B=2
not (A==B) is the same as
A ! =B

The answer is the same, True

Answer 14

You can use 'not' in the boolean logic just like '!= True' meaning if the statement is false.

Answer 15

There is a short way:
Use the ! Symbol instead of using Not, Like:
If (2 != 2):
Or
If (not ( 2 == 2)):
