The all and any functions

all and any both take an array as their input and are logical expansions of & and | for more than two variables. Essentially, they are equal to repeating & or | for all the elements of the array. Here is an example:

>>> all((True, False, True))False>>> any((True, False, False))True

In the first case, the function returns False, as there is at least one False instance in the iterable. In the second case, there is at least one True instance, so that function returns True as well.
