Returns `True` if the provided function returns `True` for at least one element in the list, `False` otherwise.
|
|
|
|
- Use `any()` in combination with `map()` and `fn` 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
|
|
```
