|
Takes any number of iterable objects or objects with a length property and returns the longest one.
|
|
If multiple objects have the same length, the first one will be returned.
|
|
|
|
Use `max()` with `len` as the `key` to return the item with the greatest length.
|
|
|
|
```py
|
|
def longest_item(*args):
|
|
return max(args, key=len)
|
|
```
|
|
|
|
```py
|
|
longest_item('this', 'is', 'a', 'testcase') # 'testcase'
|
|
longest_item([1, 2, 3], [1, 2], [1, 2, 3, 4, 5]) # [1, 2, 3, 4, 5]
|
|
longest_item([1, 2, 3], 'foobar') # 'foobar'
|
|
```
