What am I doing wrong ?
Why is the following code working and the one I use in the challenge window (item.py) not working ?
Thank you very much,
import random
iterable = input("Choose an iterable : ")
def random_item(iterable): long_iter = len(iterable) print("long_iter: {}".format(long_iter)) rand_nr = random.randint(1, long_iter - 1) print("rand_nr: {}".format(rand_nr))
print(iterable[rand_nr])
random_item(iterable)
# EXAMPLE
# random_item("Treehouse")
# The randomly selected number is 4.
# The return value would be "h"
import random
def random_item(iterable):
long_iter = len(iterable)
rand_nr = random.randint(1, long_iter - 1)
return iterable[rand_nr]
