Logical Operators: Not

Full lesson:

The logical not operator is used to invert the value of a boolean condition. For example:

7 <= 10 # Evaluates to True
not 7 <= 10 # Evaluates to False

12 != 12 # Evaluates to False
not 12 != 12 # Evaluates to True

!True # Evaluates to False

It is oftenly used with boolean variables:

hungry = True
if not hungry:
    print("I can wait a little longer")
else:
    print("I need food!")

not hungry evaluates to False, so we enter the else and print "I need food!".
