How to manage the fonc arguments through a decorator?

Question

Instead of a long awkward description, I have built an example of decorator I try to handle : check out "decor & arg _ test" on my profile, in case you would try yourself. I let some ~~ where I guess something related to arguments (and the wrap effect) should take place...

Hello. You can pass parameters through the wrapper function and use them to call the actual function, like this.

def dodg_divider(fonc) :
def wrap(x,y) :
r = fonc(x,y)
w = float(x) % float(y)
div_inaccuracy = (r-w, r+w)
return r, div_inaccuracy
return wrap

I think you should call the fonc(x, y) only once inside the wrapper. This solution is not perfect yet.. You should pay attention to type conversions and type checks. I would put the try block outside, where you get the input() and make sure you only pass integers to the function. You can also avoid ValueError that way (if a float lile 5.2 is given). And design the return value so that it makes sense... Now it is a tuple that contains the function return value, and another tuple having the calculations inside the wrapper.
