lambda - applying beta-reduction (call func that returns func) to get an abstraction (function) in python -


i wrote simple example of im trying :

class test:     @staticmethod     def mul(x,y):         return x*y     func1 = staticmethod(lambda y: test.mul(y,2))     func2 = staticmethod(lambda y: staticmethod(lambda x: test.mul(y,x))) print test.func1(2) print test.func2(2)(3) 
print test.func2(2)(3)

typeerror: 'staticmethod' object not callable

i expecting second line print 6 (as 3*2), how right?

well easier thought :

class test:     @staticmethod     def mul(x,y):         return x*y     func1 = staticmethod(lambda y: test.mul(y,2))     func2 = staticmethod(lambda y: lambda x: test.mul(y,x)) print test.func1(2) print test.func2(2)(3)

this works
