Inserting a newline every 40 characters isn't working (but no errors)

Question

I'm trying to insert a newline every 40 characters. I'm very new to Python so I apologize if my code is messed up.

def wrap(msg):
   pos = 0
   end = msg
   for i in end:
       pos += 1
       if pos % 40 == 0:
           print(pos)
           end = end[:pos] + "\n" + end[:pos + 2]

   return end

This code doesn't work and there isn't any errors. I'm not sure why this happens. It seems to just return the full string??

one other way to do this would be to split the text and join the result : `splitted = "\n".join([msg[i:i+40] for i in range(0, len(msg), 40)])` see [this](https://stackoverflow.com/q/9475241/2614364) — Bertrand Martel, Sep 27 '20 at 20:58

def wrap(msg):
    res = ''
    t = len(msg)//40
    for i in range(t):
        start = i*40
        end = (i+1)*40
        res += msg[start:end]+'\n'
    res += msg[t*40:(t+1)*40]
    return res
