When we change a value to its opposite with not, we negate it, like here with not True.
print(not True)
The not operator before False changes its value. If a value is not False, it has to be True. We can see it here by displaying not False.
print(not False)
We can use the not operator with variables to negate their values. By displaying not available here, we'll see its negated value.
available = True
print(not available)
We can save a whole negation in another variable, too. Like here is_evening should store the value of not morning.
morning = True
is_evening = not morning
print(is_evening)
