I can’t find the difference between the unit test test_create_spend_chart and my implementation of it.

It would help if you provided a link to your code and the actual diff provided by the test suite, but it looks like you have the wrong number of spaces at the end of each line.

That’s rude of the test suite.

+  0| o  o  o 
-  0| o  o  o

If I manually recreate a line of what the diff would be, it looks like your lines are one space too short.

All right, thanks for the help.
Do you know of a way to contact the freeCodeCamp staff? I would like to prevent this issue in the future for other people.

I’m not sure what you mean by ‘prevent this issue’? What do you have in mind? You could make a suggestion as a GitHub Issue.

‘Issue’ being that a missing space at the end of a line is considered a mistake by the system. I don’t understand it. Thanks for all your help though!

It’s part of the spec for the problem. If we diff your string and the output, we have to have character for character agreement. I don’t know how we could easily check for an arbitrary number of spaces after each line.

I think they tried to warn about this in the test suite:

I understand. It just annoyed me because I couldn’t understand the issue. Thanks again for your help and for explaining all my questions.
