4,344 PointsRandom Choices help
Hey everyone,
I'm stuck on a code challenge.. The error message Treehouse is giving me is that nchoices() isn't defined. Which confuses me. But really what I'm confused about is making the length n, I understand the concept of n just not how to apply it.
Thanks in advance
import random
def nchoice(iterable, interger):
my_list = []
for item, number in enumerate(iterable):
random_item = random.choice(iterable, interger)
my_list.append(random_item)
return list

It looks like you have mutliple issues here:
- The challenge asked for nchoices (with an "s"), but you defined nchoice
- the integer argument specifies how many (n) choices to return, so use it in a range for your loop
- you won't need enumerate
- random.choice needs only the iterable as its argument
- the return should pass back the constructed list (my_list)
I'll bet you can fix it now without an explicit spoiler.

2,766 Pointsyou did some good work. if i can give you some hints: the for loop you wont use, because you really want to repeat the value of the integer. like integer = 5 -> you want to run it 5 times depending on nothing else. better use other loop ;)
also you want to do the random.choice function only on the iterable, which you want to split first with split()
i am a beginner too i hope its a bit helpful
