Python Python Collections (Retired) Dungeon Game Random Choices

why doesn't my code work?

  • Create a function named nchoices() that takes an iterable and an integer. The function should return a list of nrandom items from the iterable where n is the integer. Duplicates are allowed.

my code:

def nchoices(iterable, n):
  n_list = []
  number = int(n)
  # get the random item from the list

#put n random items in the list
while number > 0:
  random_item = random.choice(iterable)
  number -=1

#return the list
return n_list

What output are you getting, which you weren't expecting? From looking at your code:

  1. You need to import random in order to use it (which maybe you did and didn't copy and paste)
  2. Your while and return should be indented - otherwise they're not part of the function
  3. Instead of a while loop and decrementing (count n down) - I would use the range() function, which does the work for you. This is built in to do loop management for you.
import random
def nchoices(iterable, n):
    n_list = []
    for _ in range(n):
        ##do the choosing and appending here
    return n_list

Here how I did it

import random
def nchoices(iterable, count):
    lst = []
    for x in range(count):
    return lst
