python 3.x - Finding and returning the value at location index in a list -


could current code work function? here goal of trying first , current attempt

look @ list of values, xs. find , return value @ location index. when index invalid xs, return response instead.

current code: 

def get(xs, index, response=none):     xs=[]     i=0     in xs:         try:             while i<len(xs):                 index=xs.index(xs,index)                 index =             return          except:             return response

thanks appreciated

you seem confused trying do...

so if understand correctly want return xs[index] if exists otherwise response, simple way following eafp principle is:

def get(xs, index, response=none):     try:         return xs[index]     except indexerror:         return response
