### compact
|
|
|
|
Removes falsey values from a list.
|
|
|
|
Use `filter()` to filter out falsey values (False, None, 0, and "").
|
|
|
|
```python
|
|
def compact(arr):
|
|
return list(filter(lambda x: bool(x), arr))
|
|
```
|
|
|
|
``` python
|
|
compact([0, 1, False, 2, '', 3, 'a', 's', 34]) # [ 1, 2, 3, 'a', 's', 34 ]
|
|
``` |
