How to test if a class attribute is an instance method
attributes, instance, methods, python
Solution
def hasmethod(obj, name):
return hasattr(obj, name) and type(getattr(obj, name)) == types.MethodType
Problem
In Python I need to efficiently and generically test whether an attribute of a class is an instance method. The inputs to the call would be the name of the attribute being checked (a string) and an object. hasattr returns true regardless of whether the attribute is an instance method or not. Any suggestions? For example: ``` class Test(object): testdata = 123 def testmethod(self): pass test = Test() print ismethod(test, 'testdata') # Should return false print ismethod(test, 'testmethod') # Should return true ```
