As expected, pep8 complains about this recommending usage of isinstance(). Now, the problem is that the numbers module was added in python 2.6 and i need to.

May 2, 2021classes in python do also have information about their subclasses - the c-level pytype_ready function informs the base classes about a subclass while readying the subclass.. Isinstance(x, (types.functiontype, types.builtinfunctiontype, types.methodtype, types.builtinmethodtype, types.unboundmethodtype)) i compared this with the code of is*() checks. Oct 4, 2014for the following code, str is variable of unicode type but str is unicode # returns false isinstance(str, unicode) # returns true why is is return false?
