Syntax error in base.py under Python 3 #638

Open timrprobocom opened 2 years ago

Line 193 in base.py has 

           raise TypeError, ("Both weights and assigned values must be a "
                              "sequence of numbers when assigning to values of "
                              "%r. Currently assigning value(s) %r of %r to a "
                              "fitness with weights %s."
                              % (self.__class__, values, type(values),
                                 self.weights)), traceback

That's the Python 2 syntax. For Python 3, that first comma needs to be removed.

@timrprobocom I've created a Python 3.10 port of the DEAP library called DEAP-er. It's currently in beta, but you could check it out and provide feedback about any bugs.
