Question

This is probably a stupid question, but what’s the best way to clear class variables between instances?

I know I could reset each variable individually in the constructor; but is there a way to do this in bulk?

Or am I doing something totally wrong that requires a different approach? Thanks for helping …

class User():
    def __init__(self):
        #RESET ALL CLASS VARIABLES

    def commit(self):
        #Commit variables to database

>>u = User()
>>u.name = 'Jason'
>>u.email = '[e-mail]'
>>u.commit()

So that each time User is called the variables are fresh.

Thanks.

Can you just pass the parameters into the constructor like this?

class User(object):
    def __init__(self, name, email):
        self.name = name
        self.email = email
    def commit(self):
        pass

jason = User('jason', '[e-mail]')
jack = User('jack', '[e-mail]')

There’s nothing to “reset” in the code you posted. Upon constructing a user, they don’t even have a name or email attribute until you set them later. An alternative would be to just initialize them to some default values as shown below, but the code I posted above is better so there won’t be any uninitialized User objects.

def __init__(self):
    self.user = None
    self.email = None
