I'm using python 2.7.10 to follow a flask tutorial being delivered using python 3.4. I'm aware of some differences between the two versions, but seems that knowledge typeerror error when calling the metaclass bases object() takes no parameters isn't enough to overcome this situation. I have amateur level experience in python. Have a feeling its got something to do with class definition, but unable to nail it. And yes i went through the solutions for similar error but wasn't able to relate the solution to my problem. Traceback (most recent call last): File "manage.py", line 5, in

So simply make the super call: return super(MyMeta, cls).__init__(name, bases, dct) Another solution is to avoid the super call altogether and do this (although it's a little less nice): return type.__init__(cls, name, bases, dct) And everything will work fine (in python >= 2.6). As to why type.__init__() can take differing numbers of arguments, check out the documentation. It's so that as well as using it as a constructor, you can call type(myobject) and it will return the type of myobject: >>> number = 1 >>> type(number)

These Aren't Roasted! Join Date Aug 2005 Beans 169 Python problem inheriting metaclass So I finally decided to try this python thing you all keep going on about! I've been trying to inherit a class (that I've called "player") from xmms.control, which itself turns out to be a metaclass. A simple script: Code: from xmms import control class hello: __metaclass__ = control def hellomethod(self): print "hello" hello().hellomethod() produces the following error: Code: Traceback (most recent call last): File "hello.py", line 2, in ? class hello: TypeError: Error when calling the metaclass bases 'module' object is not callable I'm presuming that xmms.control is a metaclass because if I try inheriting it with the line "class player(control):", I get error messages relating to metaclasses. Can anyone tell me what I'm doing wrong? Adv Reply January 15th, 2006 #2 cwaldbieser View
