What does all mean in Python?
In Python, the all() function returns True if all elements of an iterable (e.g. list, tuple, etc.) are true, and False otherwise. For example:
>>> all([True, True, True])
True
>>> all([True, False, True])
False
An empty iterable returns True.
>>> all([])
True
It can also be used on a generator object.
>>> all(i > 2 for i in [1, 2, 3, 4])
False
It is equivalent to the following code:
>>> def all(iterable):
... for element in iterable:
... if not element:
... return False
... return True
