Equivalent of `-s` when calling pytest with pytest.main()

I am calling in my script, pytest.main(); although I get no print out unless the test fail.

I know that pytest has a -s flag that solve the problem, and in fact if I call my test from console using

python3 -m pytest -s mytest.py

Works just fine and I get the print statements printed correctly even if the test pass; but I can't find how do you obtain the same outcome while calling pytest.main() from a python script.
