Dictionary in Python (5)

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 (4).
• 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 only all the keys or both all the keys and values in:

• the dictionary are in other dictionary with <=.
• the dictionary and only other keys or both other keys and values are in other dictionary with <.
• other dictionary are in the dictionary with >=.
• other dictionary and only other keys or both other keys and values are in the dictionary with >.

*Memo:

• Only all the values cannot be checked.
• dict.keys() and dict.items() work for all <=, <, >= and >.
• dict and dict.values() get error for all <=, <, >= and >.

A dictionary and other dictionary can be checked if they have and don't have only their common keys or both their common keys and values with bool() and & and with not keyword and & respectively as shown below:

*Memo:

• Only their common values cannot be checked.
• dict.keys() and dict.items() work.
• dict and dict.values() get error.
