Uh, what? I can sort of guess what you are referring to here (namely, that no syntactic construct permissible in a lambda can assign to a local variable -- or any variable, for that matter).
That's not even quite true, you can assign to global variables in a lambda:
myglobal = 1 f = lambda: globals().__setitem__('myglobal', 2) or 42 f() myglobal 2
