An example code for the task "Compare length of two strings" (Rosseta Code).
print('"' + str1 + '"', 'has length', len(str1), 'and is longer')▼
This example code can handle not only strings, but any objects.

"""
For objects given as parameters it prints which of them are the longest.
So if the parameters are strings, then the strings are printed, their
lengths and classification as the longest, shortest or average length.
Note that for N> 0 such objects (e.g., strings, byte strings, lists) it is
possible that exactly M> 0 of them will be of the maximum length, K> 0 of
them will be of the minimum length. In particular, it is possible that all
objects will be exactly the same length. So we assume that if an object has
both the maximum and minimum length, it is referred to as a string with the
maximum length.
Args:
*objects (object): Any objects with defined length.
sorted_ (bool, optional): If sorted_ is False then objects are not
sorted. Defaults to True.
reverse (bool, optional): If reverse is True and sorted_ is True
objects are sorted in the descending order. If reverse is False
and sorted_ is True objects are sorted in the ascending order.
Defaults to True.
Returns:
None.
