To me your version is less clearer than the explicit if calls: * Name 'map' for a variable is a poor choice (as it has same name as the python builtin function map) * Your version has off by one error, it doesn't give correct results when called with a single element list or if the list has three elements: >>>mymap = [ lambda args: (0, args[0], 1), lambda args: (args[0], args[1], 1), lambda args: args, ] >>>args = [5] >>>mymap[len(args)](args) IndexError Traceback (most recent call last) .... # This shouldn't be the case, a list with a single # element is a valid input >>>args = [1,6,1] >>>mymap[len(args)](args) IndexError Traceback (most recent call last) ... # This shouldn't be the case, a list with a three # elements is a valid input
