What is the probleme in my random ?

You are getting two random numbers and storing both of them separately. To print / return an item at a specified index do this:

single[0]  # put the number of the index you want to return in brackets. In this case the first item will be returned
single[random_number]  # here we return the random index

# for example your last line would be
print("The return value would be {}.".format(single[random_number]))

Thanks !

import random

def random_item(single):
    # put the number of the index you want to return in brackets. In this case the first item will be returned
    single[0]
    random_number = random.randint(0, len(single) - 1)
    print ("The randomly selected number is {}".format(random_number))
    # for example your last line would be
    print("The return value would be {}.".format(single[random_number]))

i finish the code like that it is good ?

If I gave you a list named numbers and it looked like this: [5, 3, 1, 7, 9] how would you print out the 3rd item in the list?

numbers[2]

What if I had a list named favorite_teachers and it looked like this ["Kenneth Love", "Pasan Premaratne"] and I asked you to pick a random teacher from the list. How would you do that?

# multiple choice
# A:
random_teacher = random.randint(0, len(favorite_teachers))

# B:
random_teacher = random.randint(0, len(favorite_teachers) - 1))

# C:
random_teacher = random.randint(1, 2)

# D:
random_teacher = favorite_teacher[2]

SOu TO,

Let's break that answer down.

len(favorite_teachers)

This will return 2 because there are two teachers in the list of favorite_teachers. This means our random number generator will generate a 0, 1, or a 2. This is like me saying pick a number from 0 to 2.

Let's say the computer picks 0, which teacher do you think that is?

favorite_teachers[0]  # this would return 'Kenneth Love'

What if the computer picks 1?

favorite_teachers[1]  # this would return 'Pasan Premaratne'

I hope this is making since. But what happens if the computer picks 2? There isn't a teacher at index 2. For this reason, the answer is:

# B:
random_teacher = random.randint(0, len(favorite_teachers) - 1))

If you'll notice the -1 part here:

len(favorite_teachers) - 1

This looks like this: Count how many items are in favorite_teachers and subtract one from that. Why do we do this? This is because computers start counting from 0. That means the first item in an iterable is at index 0 and in the example of favorite_teachers there are only two items. The item at index 0 and the item at index 1.

I hope this helps. Let me know if you have any questions.
