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