Answer 1

The test that is failing is NOT importing YOUR fuel.py. It is testing YOUR test_fuel.py against the check50 test version of fuel.py (called the "correct fuel.py" in the link). That way check50 knows fuel.py is correct.

One or more of your tests return exit code 2 instead of 0, so are considered failing. You have to isolate the test that does this. The best way I found is to run check50 with only 1 test function in test_fuel.py. If it passes the "correct fuel.py" test, it's OK. [Ignore errors for latter tests that you haven't implemented yet.] If doesn't, fix the test function until it does. Then, continue the process: add another test function, test it, and repeat until all tests pass. Eventually you will find the culprit. Good luck.

Answer 2

Clearly, it isn't working fine. It's failing the first test. Without seeing any code, there's no way to tell why.

The check50 run provides a link to the test results. Go to it and look at the details of why it fails. Also, try running the program locally, using the data used in the test.
