function - Error instantiating a class in Python -

i'm attempting instantiate class:

class customer(object):     def __init__(self, name, money, ownership):         self.name = name         self.money = money         self.ownership = ownership      def can_afford(self):         x = false         bike in bikes.values():              if self.money >= bike.money * margin:                 print "customer {} can afford {}".format(self.name, bike)                 x = true         if not x:             print "customer {} cannot afford bikes @ time.".format(self.name)  shoppers = {             # initial condition of shopper1     "jane": customer("jane", 200, false),     # initial condition of shopper2     "alfred": customer("alfred", 500, false),     # initial condition of shopper3     "taylor": customer("taylor", 1000, false) }  buyer = customer(name, money, ownership) 

but buyer = customer(name, money, ownership) keeps getting errored:

undefined variable 'name' undefined variable 'money' undefined variable 'ownership' 

but thought set variable's values in dictionary "customer(...)"

class customer(object):     def __init__(self, name, money, ownership):         self.name = name         self.money = money         self.ownership = ownership      def can_afford(self):         x = false         bike in bikes.values():              if self.money >= bike.money * margin:                 print "customer {} can afford {}".format(self.name, bike)                 x = true         if not x:             print "customer {} cannot afford bikes @ time.".format(self.name)  shoppers = {             # initial condition of shopper1     "jane": customer("jane", 200, false),     # initial condition of shopper2     "alfred": customer("alfred", 500, false),     # initial condition of shopper3     "taylor": customer("taylor", 1000, false) } #this solution mentioned problem name = 'buddy'  money = 2 ownership = 'something' buyer = customer(name, money, ownership)  

solution mentioned problem above, need define values. there other issues well, bikes.values(), came?

remember, use something, have first tell is, define things.

hope helps.
