There is an extra piece of code in the pypi.org packages

If I install a package with pip install czech-workdays-holidays and then want to use it with import, this string is always output:

The archive czech_workdays_holidays-0.1.11.tar.gz on pypi.org contains this line of code in the file czech_workdays_holidays.py:

print(get_workdays_during_weekend(2023, include_holidays=False))

Probably a leftover from the testing? It makes this library quite difficult to use.
