any() function in Python with a callback
any, callback, functional-programming, python
Solution
How about:
>>> any(isinstance(e, int) and e > 0 for e in [1,2,'joe'])
True
It also works with `all()` of course:
>>> all(isinstance(e, int) and e > 0 for e in [1,2,'joe'])
False
Problem
The Python standard library defines an `any()` function that Return True if any element of the iterable is true. If the iterable is empty, return False. It checks only if the elements evaluate to `True`. What I want it to be able so specify a callback to tell if an element fits the bill like: ``` any([1, 2, 'joe'], lambda e: isinstance(e, int) and e > 0) ```
