Python: Take any number of iterable objects or objects with a length property and returns the longest one

Python Regular Expression: Exercise-56 with Solution

Write a Python program that takes any number of iterable objects or objects with a length property and returns the longest one.

  • Use max() with len() as the key to return the item with the greatest length.
  • If multiple objects have the same length, the first one will be returned.

Sample Solution:

Python Code:

def longest_item(*args):
  return max(args, key = len)
 
print(longest_item('Red', 'Green', 'Black', 'Orange'))
print(longest_item([1, 2, 3], [1, 2, 3, 4], [1, 2, 3, 4, 5]))
print(longest_item([1, 2, 3], 'Java'))
print(longest_item({10, 100}, 'Python'))

Sample Output:

Orange
[1, 2, 3, 4, 5]
Java
Python
