Python not Keyword
The not keyword in Python is used when we need to inverse the boolean value of evaluated expression. That is, the not keyword returns True, if the expression evaluates to be False, otherwise returns False, if the expression evaluates to be True. For example:
print(not True) print(not False)
The output is:
False True
Python not Keyword Truth Table
The truth table of not keyword in Python, is:
X | not X |
---|---|
True | False |
False | True |
Python not Keyword Example
Here is an example of not keyword in Python:
print("Enter the Two Number: ", end="") numOne = int(input()) numTwo = int(input()) x = numOne>numTwo if not x: print("\nThe value", numOne, "is greater than", numTwo) else: print("\nThe value", numTwo, "is greater than", numOne) print("\n\n\n@April Fool")
The snapshot given below shows the sample run of above program, with user input 10 and 30 as first and second numbers:
The not keyword in above program, reversed the result or output.
