Python: Find the longest one from any number of iterable objects or objects with a length property

Python List: Exercise - 245 with Solution

Write a Python program to 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('this', 'is', 'a', 'Green'))  
print(longest_item([1, 2, 3], [1, 2], [1, 2, 3, 4, 5])) 
print(longest_item([1, 2, 3, 4], 'Red'))

Sample Output:

Green
[1, 2, 3, 4, 5]
[1, 2, 3, 4]

Floor Division:

When we speak of division we normally mean (/) float division operator, this will give a precise result in float format with decimals.

For a rounded integer result there is (//) floor division operator in Python. Floor division will only give integer results that are round numbers.

print(1000 // 300)
print(1000 / 300)

Output:

3
