Use super() to call up to the base class, and then add the extra bits
pertaining to the derived class.
That is, add this to your Developer subclass:
def __str__(self):
sup = super().__str__()
return '{} "{}")'.format(sup, self.ProgLang)
You'd need to do a little bit of work to clean up the output, as the
string representation returned by the base class is already closed with
a paren (see second line of output below):
("Abigail" "Buchard" "83000")
("Samson" "Sue" "63000") "Cobol")
("Samson" "Sue" "63000" "Cobol")
but it should show a way to approach this problem, anyway
