title: Python Any Iterable
|
|
---
|
|
`any()` is a built-in function in Python 3 (and Python 2 since version 2.5), to check if any of the items of an <a href='https://docs.python.org/3/glossary.html#term-iterable' target='_blank' rel='nofollow'>_iterable_</a> is `True`. It takes one argument, `iterable`.
|
|
|
|
## Argument
|
|
|
|
### iterable
|
|
|
|
The `iterable` argument is the collection whose entries are to be checked. It can typically be a `list`, `str`, `dict`, `tuple` etc., even a `file object`.
|
|
|
|
## Return Value
|
|
|
|
The return value is a Boolean. If and only if **all** entries of iterable are `False`, or the `iterable` is empty; it returns `False`. This function essentially performs a Boolean `OR` operation over all elements.
|
|
|
|
If even one of them is `True`, it returns `True`.
|
|
|
|
The `any()` operation is equivalent to (internally, may not be implemented exactly like this)
|
|
|
|
def any(iterable):
|
|
for element in iterable:
|
|
if element:
|
|
return True
|
|
return False
|
|
|
|
## Code Sample
|
|
|
|
print(any([])) #=> False
|
|
print(any({})) #=> False
|
|
print(any([None])) #=> False
|
|
print(any(['', {}, 0])) #=> False
|
|
print(any([6, 7])) #=> True
|
|
print(any([6, 7, None])) #=> True
|
|
print(any([0, 6, 7])) #=> True
|
|
print(any([9, 8, [1, 2]])) #=> True
