Introduction
In this challenge, you will write a function that takes any number of iterable objects or objects with a length property and returns the longest one.
Longest Item
Write a function longest_item(*args) that takes any number of iterable objects or objects with a length property and returns the longest one. The function should:
- Use
max()withlen()as thekeyto return the item with the greatest length. - If multiple items have the same length, the first one will be returned.
def longest_item(*args):
return max(args, key = len)
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'
Summary
In this challenge, you learned how to write a function that takes any number of iterable objects or objects with a length property and returns the longest one. You used max() with len() as the key to return the item with the greatest length. If multiple items have the same length, the first one will be returned.
