Keywords: and, or, not
There are some keywords for Boolean variables: and, or, not. They exist to create more complex expressions. Next we will see how it works with examples.
- and. If value x = True and value y = True then x and y is equal to True. If either of those is False, then expression becomes False too.
- or. If x = True or y = True then the expression x or y is equal to True (or both values = True).
- not If value x is False then the expression, not x evaluates to True . Otherwise, the expression evaluates to False.
Input:
x, y = True, False
print((x or y) == False)
Output:
False
Input:
x, y = True, False
print((x and y) == False)
Output:
True
Input:
x = False
print(not x)
Output:
True
