Python's all(~) method returns a boolean indicating if all the elements of the input iterable are true.

Parameters

1. iterable | iterable

The iterable to check whether elements are true for.

Return value

A boolean indicating if all the elements of the input iterable are true. Also if the iterable is empty True is returned.

Examples

To check whether all elements in list x are true:

x = ['cake', 'cookie', 'cupcake', ['pudding','tea']]
all(x)
True

To check whether all elements in dictionary y are true:

y = {0:'zero', 1:'one', 2:'two'}
all(y)
False

As 0 is false, not all elements in the dictionary are true hence False is returned.

To check whether all elements in set z are true:

z = {}
all(z)
True

As the set is empty, True is returned.
