int is not a function but a type, but it's callable so int(0) return 0.

lambda is a function, applied as a class attribute it becomes a method so it's
called with a first parameter representing the instance, self.f(0) in the
__init__ becomes C2.f(self, 0), so the lambda should be :
f = lambda s, x: x != 0 # s for self, some poeple use _
this exactly the same as :
def f(self, val) :
return x != 0
(that lambda will return True or False i expect this is not what you want)
