Question

I know that I can’t overload functions in python, and I can’t seem to get my head around using python to get the behavior I’m after.

An Example:

class Hop(object):
   def __init__(self, variety, aa, qty, time):
      self.variety = variety
      self.aa = aa
      self.qty = qty
      self.time = time

class HopBill(object):
   hop_list = []
   def add(self, hop):
      self.hop_list.append(hop)
   # Where I would put an overloaded function?
   def add(self, variety, aa, qty, time):
      self.hop_list.append(Hop(variety, aa, qty, time))

I’m not really crazy about just using kwds and just adding a bunch of logic to decode what inputs my function received.

I’m getting the feeling there is a way better way of setting this up, anyone have any advice on how to take a more pythonic approach?

Thanks!

Just make two methods. Init hop_list in __init__ or the instances of HopBill will share the list:

class HopBill(object):
   def __init__(self):
       self.hop_list = []
   def add(self, hop):
      self.hop_list.append(hop)
   def addnew(self, variety, aa, qty, time):
      hop = Hop(variety, aa, qty, time)
      self.add(hop)
