Checks if the provided function returns `True` for at least one element in the list.
- Use `any()` in combination with `map()` to check if `fn` returns `True` for any element in the list.
```py
def some(lst, fn = lambda x: x):
return any(map(fn, lst))
```
```py
some([0, 1, 2, 0], lambda x: x >= 2 ) # True
some([0, 0, 1, 0]) # True
```
