Front End Web Development Techdegree Student 2,190 PointsI have a trouble with a list..
In this task , this function takes a list and int number and it returns a list... My question is, what does the first list does? i mean..if the return is a list with a max of numbers, why we need it if we can create a list with random inside the function?
if somebody can explain it me better I will be able to reach the challenge :)
Thanks! Alex
import random
def nchoices(llista, num):
items = random.choice()

def nchoices(llista, num):
what you should do in the function body is
- first create an empty list to hold the result
- pick a random number from llista, append it to the result list, keep doing that num times.
- after that, return the result list as the return value of the function.

random.choice(llista)
That will return you 1 randomly picked element from llista
