How to find max and min of a list using a recurring function

By recurring function I mean a function that works like a loop: the one that calls herself at the end... PS: i know the name in frensh as "fonction récursive" but i am not sure regarding its technical name in english 🤔 Please help, if u understood my unclear question of course 😅

So here is mine pretty ugly but still working solution: https://code.sololearn.com/cz66oXF1G3bQ/?ref=app Also has error catching Btw. it uses similar principle as your loop code just put to recursion Pls. all comment any error, i am interested in this one

In python it doesn't require to use recursive function. It had functions max() and min(). These return respectively maximal and manimal value from list passed as argument.

It is called recursive function And in what language, becase some of them have predefined functions for this

If you had to use a loop instead of a recursive function, could you solve it yourself?

Jared Bird Yes of course i've already done that before L=list(input('write a numeric list') Max =L[0] While i in range(len(L)) : If L[i] >Max : Max=L[i] Print(Max)

Ok, so one way would be close to this. Could you write a function that removes 1 item from the list, then calls it's self until there is 1 left and this is the max?

@maneren Here is my attempt to code it using a recursive function Def max (L) : If L==0: return 0 return max(L.del(L[0]))

Maneren you ready to give the answer away already? BTW it does not work for a list of negative integers.

Maneren I hope you are not taking it personally. It's just when it's for some else's home work I prefer to give hints and not write the code for them.

Jared Bird ok, get it and no problem i am just little bit more straightforward PS. i gave just the idea, as you mentioned it doesn't work for negative, and also is just for max not min So asker has to work on it little bit
