Tell us what’s happening:

Why the answer didn’t come, there’s an error in my codes, can you help me please

Your code so far

print this, use print, you are missing quite a lot in your output

Faiht · June 11, 2025, 2:18am

Okeyy thanks, but why the progress didn’t complete yet, the output come with correct answer

ILM · June 11, 2025, 7:24am

no, your output is not correct

for print(arithmetic_arranger(["3801 - 2", "123 + 49"])) it shows:

that is not correct.

if you have made changes and still want help, please post your updated code

Help, I begginer with this all, can you help me please, how to start to divide the code to 3 form, i tried but it return error, can you help me check what’s wrong with that

Your code so far

Here are some troubleshooting steps you can follow. Focus on one test at a time:

Are there any errors or messages in the console?
What is the requirement of the first failing test?
Check the related User Story and ensure it’s followed precisely.
What line of code implements this?
What is the result of the code and does it match the requirement? (Write the value of a variable to the console at that point in the code if needed.)

If this does not help you solve the problem, please reply with answers to these questions.

Hi @Faiht

I went ahead and combined your posts for you. In the future, just reply to the original thread to add further updates.

Thanks.

Can you help me this code didn’t work well, the exam didn’t checklist correct them

Faiht · August 24, 2025, 9:52am

ILM · August 24, 2025, 10:37am

if you use repr() around the call to arithmetic_arranger you can confront the output with the string shown in the hints

Faiht · August 24, 2025, 1:20pm

Same condition, how it can’t work ? I think that’s literly complete

I’ve tried rpr(), and another solution to complete this Project, but the checklist didn’t correct it until now, can anyone help with with solution please

Please say what specific tests you are not passing and what you have tried to fix them.

Note - the code submitted for these projects must be your own.

pkdvalis · August 24, 2025, 2:16pm

Use repr() like this:

 print(repr(arithmetic_arranger(["3801 - 2", "123 + 49"]))

You should see the output in the same format that the tests display.
