Vending Machine Selection Malfunction

Question

So, can someone help me with the solution? This is what I have so far, but I keep getting EOFErrors:

products = ["Water", "Chocolate", "Chips", "Soda", "Sandwich"]
choice_index = int(input(8))
try:
print()
# Write a try-except block to display the selected product
except IndexError:
print("Wrong Index")
# or print "wrong index" if the input index is out of range

Answer 1

CodingTranslater638 ,

in the current code the upper bound of the index is `hard-coded` (5). giving an input of `5` will raise an IndexError, because the highest correct index for the current list is `4`

it is recommended to use the len(...) built-in function instead of the number of `5`.

also the comparison operator should be `<` instead of `<=`

> in general we should use a solution that implements a try... except... statement like:

...
try:
print(products[num])
...

Answer 2

Where would this code display the selected product?

Answer 3

1. Remove 8 from the input
2. Print the product at choice_ondex in the try-block
3. Check the spelling of the message in the except-block

Answer 4

Lothar thanks!

Answer 5

In the try block, I'm not sure how to show the string paired with any available indexes

Answer 6

Thanks Lisa, ill try that

Answer 7

I have found the answer! It was this code for a different Vending Machine code, so I used that and changed it for it to work for my code! This was the winning code:

products = ["Water", "Chocolate", "Chips", "Soda", "Sandwich"]
num=int(input())
if num>=0 and num <=5:
print(products[num])
else:
print("wrong index")
