Removes falsy values from a list.
|
|
|
|
- Use `filter()` to filter out falsy values (`False`, `None`, `0`, and `""`).
|
|
|
|
```py
|
|
def compact(lst):
|
|
return list(filter(None, lst))
|
|
```
|
|
|
|
```py
|
|
compact([0, 1, False, 2, '', 3, 'a', 's', 34]) # [ 1, 2, 3, 'a', 's', 34 ]
|
|
```
