With some assumptions, It will be useful for every function call:-) If PEP 572 [1] were to be accepted, you could do something like this: > > def func(numb): > if ((int as int), (float as float)): > res = [] > for i in range(numb): > res.append(int(i) + float(i)) > return res > > Syntactically a bit clunky, but keeps everything inside the function, > and DOES create local variables.
