Can len() be used with other types?

Yes, the len() function in Python can be used with several other types, including:

1. Lists: Returns the number of elements in the list.

   my_list = [1, 2, 3]
   print(len(my_list))  # Output: 3

2. Tuples: Returns the number of elements in the tuple.

   my_tuple = (1, 2, 3)
   print(len(my_tuple))  # Output: 3

3. Dictionaries: Returns the number of key-value pairs in the dictionary.

   my_dict = {'a': 1, 'b': 2}
   print(len(my_dict))  # Output: 2

4. Sets: Returns the number of unique elements in the set.

   my_set = {1, 2, 3}
   print(len(my_set))  # Output: 3

5. Strings: As mentioned earlier, it returns the number of characters in the string.

The len() function is versatile and can be used with any object that implements the __len__() method. If you have more questions or need examples, let me know!
