Dictionary in Python (4)

Buy Me a Coffee☕

*Memo:

• My post explains a dictionary (1).
• My post explains a dictionary (2).
• My post explains a dictionary (3).
• My post explains a dictionary (5).
• My post explains a dictionary (6).
• My post explains a dictionary (7).
• My post explains a dictionary (8).
• My post explains a dictionary (9).

A dictionary and other dictionary can be checked if all the keys and/or values in them are and aren't equal with == and != respectively as shown below:

*Memo:

• For dict.values(), == and != always return False and True respectively.
• == and != can also check if types of values are and aren't the same respectively:
  • dict.keys() and a set or frozenset and vice versa are True even though their types are different.
  • dict.items() and a set(tuple) or frozenset(tuple) and vice versa are True even though their types are different.
