Casts the provided value as an array if it's not one.
|
|
|
|
Use `isinstance()` to check if the given value is enumerable and return it by using `list()` or encapsulated in a list accordingly.
|
|
|
|
```py
|
|
def cast_list(val):
|
|
return list(val) if isinstance(val, (tuple, list, set, dict)) else [val]
|
|
```
|
|
|
|
```py
|
|
cast_list('foo') # ['foo']
|
|
cast_list([1]) # [1]
|
|
cast_list(('foo', 'bar')) # ['foo', 'bar']
|
|
```
