Random choices challenge. Need a little bit of help please.

I think i'm doing this correctly but I can't make it stop at the n integer. If someone would point me in the right direction that would be greatly appreciated! THANKS (: !

choices.py 
def nchoices(things, n):
  new_list = []
  import random
  for item in things:
    random.choice(things)
    new_list.append(things)
    # if things == len(n):
    # This is the closest way I could think of making it stop at the n integer.
    # But it doesn't seem to work and i'm confused.
  return new_list

Wow this has taken me the best part of an evening to work out! Thanks Frank your code gave me something to work from, I had been going in all sorts of crazy directions. I think the biggest thing we had been missing was a while loop.

import random
def nchoices(things, n):
  new_list = []
  for item in things:
    while n > 0:
      nl = random.choice(things)
      new_list.append(nl)
      n -=1
  return new_list

I've now come up with this. Which is giving me 26 results instead of the needed 5. All I need to do is figure out how to stop it at the 'n' integer and it should be good. Still have made no progress on that front lol.

def nchoices(things, n):
  new_list = []
  import random
  for item in things:
    random.choice(item)
    new_list = things
  return new_list

I don't think you need a for loop here; a while loop will do the trick.

import random

def nchoices(iterable_1, integer):
   new_list = []
   while integer > 0:
      new_list.append(random.choices(interable_1))
      integer -= 1
   return new_list

Also, I've found it to be best practices to do all imports at the very beginning of your code :)
