expand_more 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.
