Python: object as an argument of another object

I have a module including definitions for two different classes in Python. How do I use objects of one class as an argument of the other? Say, I have class definitions for Driver and Car, and tuen want to have a Driver object as an argument for a Car object.

If I understand your question, this will help you Assume we have class BankAccount: '''After Constructor, we have another method ''' def transfer(self,amount,object): #object is variable passed for referencing an object BankAccount.credit(self,amount) object.debit(amount)

call method bank1=BankAccount() bank1.transfer(2000,objectname)

Create an instance of a Driver object and pass it to the Car's constructor.

e.g.,

>>> d = Driver()
>>> c = Car(d)

or just

>>> c = Car(Driver())

[edit]

So you're trying to use an instance of a driver as you define a class? I'm still not sure I understand what it is you're trying to do but it sounds like some kind of decorator perhaps.

def OwnedCar(driver):
    class Car(object):
        owner = driver
        #...
    return Car

steve = Driver()
SteveCar = OwnedCar(steve)

Update: The OP is trying to pass an object instance at class definition time (or so I think after seeing his comment). The answer below is not applicable.

Is this what you are trying to achieve? 

class Car:
    def __init__(self, driver):
        self.driver = driver

class Driver:
    pass

driver = Driver()
car = Car(driver)
