Sub class throwing AttributeError rather than getting properties from super class

I have a classes ConfTest and SubConfigTest which looks like this:

class ConfTest():
    config = {
        'account': Account
    }

    def __init__(self,
                 account):
        self.account = account
        ...



class SubConfigTest(ConfTest):
    def __init__(self):
        super(SubConfigTest, self).__init__(account=self.account)
        self.path = install_test(self.ver_config)

I want SubConfigTest to have all the properties of ConfTest.

When I run my program I get this error:

super(SubConfigTest, self).__init__(account=self.account,
AttributeError: 'SubConfigTest' object has no attribute 'account'

Where am I going wrong? I feel like I must declare account somewhere in SubConfigTest but I'm not sute how or where. I only added it because if I leave it out I get an error saying:

super(SubConfigTest, self).__init__()

TypeError: init() takes exactly 2 arguments (1 given)

In line super(SubConfigTest, self).__init__(account=self.account) the part account=self.account is evaluated before calling __init__ of base class, where is the definition self.account = account, that's why the error occures. You probably forget to pass account as a parameter to SubConfigTest.__init__:

class SubConfigTest(ConfTest):
    def __init__(self, account):
        super(SubConfigTest, self).__init__(account=account)
        self.path = install_test(self.ver_config)
