CodePudding user response：

Rather than instantiating your custom classes with arguments in the parentheses, you're just making a plain tuple object. Add the name of your class that you want an instance of in front of the parentheses.

These

cm_1 = ('Tom', 'January 16', '14', 'Mami', 'To be happy')
o_1 = ('Vera', 'June 22', '16', 'Bulalo', 'Mapasakin ka <33', 'President')

Become this

cm_1 = ClubMembers('Tom', 'January 16', '14', 'Mami', 'To be happy')
o_1 = ClubOfficers('Vera', 'June 22', '16', 'Bulalo', 'Mapasakin ka <33', 'President')

CodePudding user response：

You don't instantiate your class at all, instead you are making a tuple.

To make it work, you should call class constructor:

See the difference:

some_tuple  = ('Tom', 'January 16', '14', 'Mami', 'To be happy')  # it's a tuple

print(some_tuple[1])  # It will print January 16
some_tuple.name  # ERROR: Tuple is just a sequence of values, it doesn't have properties
some_tuple.display1()  # ERROR: There is no display1 method for tuple

some_object = ClubMembers('Tom', 'January 16', '14', 'Mami', 'To be happy')  # it's object of type ClubMembers
print(some_object.name)  # OK!
some_object.display1()  # OK!
