Obviously it has to be the same as FunctionType (even more strongly than you put it: "types.LambdaType is types.FunctionType"), so I agree, it's superfluous. Maybe it's in case some other Python implementation might distinguish?? https://docs.python.org/3/library/types.html#types.FunctionType That said, though: if you want to distinguish a lambda function from a def function, you can do so with reasonable reliability using the function's name: >>> def is_lambda(f): return f.__name__ == "<lambda>" ... >>> is_lambda(is_lambda) False >>> is_lambda(lambda x: x+1) True ChrisA -- https://mail.python.org/mailman/listinfo/python-list
