Dima and Containers CF Bronze Additional Practice Grading System Bug

For some reason, the grading system says that I need to have and EOLN (I believe it stands for “End of Line”) fromat, but I am using python print statements that by default put a newline after whatever you print out. I even specifically wrote end="\n" even though it is unnecessary code to write, but it still gives the same error. I even used both Python 3.8.10 and PyPy 3.9.10, it does not fix the issue. Is this an error with the grading system, or an error with my code?
