+# Python `any(iterable)`
+
+`any()` is a built-in function in Python 3, to check if any of the items of an [_iterable_](https://docs.python.org/3/glossary.html#term-iterable) 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 would be 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 would return `True`.
+
+The `any()` operation is equivalent to (internally, may not be implemented exactly like this)
+
+```python
+def any(iterable):
+    for element in iterable:
+        if element:
+            return True
+    return False
+```
+
+## Code Sample
+
+```python
+print(any([])) #=> False
+print(any({})) #=> 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
