test: remove empty print() functions

Python tests are based on a reference output: on every run output produced by a
test compared to reference output and test become passed when both output are
equal. Perhaps empty print()'s were added as a delimeter for testscases in a
produced output, so the main purpose of these empty print() functions is a
reader's convenience. The problem with empty print's is that code become ugly.
