🔒 My IDE thinks each item in a list is a list

[clever quiver]

`def sum(*input):
nums = []
result = 0

for i in input:
    if input.count(i) == 1:
        nums.append(i)

for j in nums:
    result += j

print(result)

sum(8,8,8,1,2,3)`

This is the code I'm working with. The PC interpreter understands it just fine, the output is 6 as expected. The python codepad on my phone says result += j is an error, "unsupported operan for +=: 'int' and 'list'. I've checked to make sure the code is exactly the same and there are no errors in the indentation, still won't work.

Remember to:

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

Same python versions on both as well

The python codepad on my phone says result += j is an error, "unsupported operan for +=: 'int' and 'list'.
Can you send a screenshot of this?

[clever quiver]

Sure

Weirdly enough, it executes just fine outside of the challenge tab

[strong moss]

according to the error message, sum([]) is being called

so input is a list of lists

[clever quiver]

I don't know what that means 😅

[strong moss]

try running sum([])

[strong moss]

there you go, your program isn't designed to handle lists as input

[clever quiver]

Weird..I tried just not calling the function and got this

...I think that means I got the exercise right?

[pulsar dew]

the example snippet only showed integers as input, not lists

[strong moss]

does it work in the "challenge tab"?

[clever quiver]

it did once it stopped working now

[pulsar dew]

what is this code user_result = sum([])?

[strong moss]

it looks like some kind of autograder

[clever quiver]

the goal is to add all the numbers that aren't being repeated

I just realised it actually never worked in the exercise tab. It worked outside of it though. Is it safe to assume the app is just buggy and for all intents and purposes, I solved the exercise correctly?

[hearty gust]

I think the issue is the grader probably isn't calling sum(1, 2, 3), I think it's calling sum([1, 2, 3])

[clever quiver]

but why ?

[hearty gust]

check to make sure you read how it's going to call your function correctly

[clever quiver]

im not sure how to do that

[hearty gust]

I mean, read the problem that you're trying to solve again

it should include an example or description on how the grader will call your function

[clever quiver]

Oh I see what you mean, this was the prompt

[hearty gust]

yeah

so the grader is calling sum([1, 2, 3])

and so you're *args is turning that into a list of lists, hence your issue

[clever quiver]

OH I should just remove args

I was going on a whole tangent to split the input into a list of integers and realising that made no sense either

typcasting result as an integer only worked outside of the exercise tab again

I did it, just changed print() to return lol
