> How does CPython display the source for tracebacks in Cython modules? Do you mean the "python" command-line program? That uses a different algorithm: to find a file FOO, it searches [os.path.join(p, os.path.basename(FOO)) for p in sys.path] This is completely broken because it ignores all leading path components of FOO. So it will only work if your file is in the root of your package, not in a subdirectory.

Do you mean the "python" command-line program? That uses a different algorithm: to find a file FOO, it searches

[os.path.join(p, os.path.basename(FOO)) for p in sys.path]

This is completely broken because it ignores all leading path components of FOO. So it will only work if your file is in the root of your package, not in a subdirectory.
