Izzy the Iguana Issue - Test Case 4

Question

I have the following code written for the Iguana issue yet test case 4 keeps failing, I know you can do this in other ways e.g. for n in snacks, if n == 'Lettuce' or writing a dictionary and use .get.

But I want to know why this doesnt work

CODE

snacks = input()

snacks = snacks.split()

total = 0

for n in range(len(snacks)):
if 'Lettuce' in snacks:
total += 5
elif 'Carrot' in snacks:
total += 4
elif 'Mango' in snacks:
total += 9
elif 'Cheeseburger' in snacks:
total += 0

if total >= 10:
print ("Come on Down!")
print (total)
else:
print ("Time to wait")

Answer 1

Owain Hayes ,

there are several issues that should be fixed:

> the for loop is generating numbers that are never used. better to run the loop like:
for snack in snacks:
...

> the conditional statements should now be compare the *snack* variable like e.g.:
if snack == 'Mango':
...

> when printing the output, we should *not* use the line:
# print(total) this output is not required.

Answer 2

Have you run the code yourself in the code playground? What happens if there are 2 or more of one of the items?

Answer 3

Owain Hayes ,

the code fragment in your last post should be:

for n in snacks:
if n == 'Lettuce':
....

or better use a meaningful variable name:

for snack in snacks:
if snack == 'Lettuce':
....

Answer 4

Lothar yeah so like I already mentioned in my post? “for n in snacks, if snacks == ‘Lettuce’?”

I am just wondering why this particular code doesnt fulfill all requirements? Whilst it could be done alrernatively as I mentioned, I dont see whats wrong with it functionally?

Also yeah my bad I just ran that in a test to see if it was generating the totals correctly, in my attempts print(total) was not included

Answer 5

Ausgrindtube, yeah I did that and it still runs fine, thats why I cant figure out what test case 4 could be that is leading to the fail
