Looking for a streamlit module function call that does the same as `streamlit run page.py` shell command

Greetings,

I learned that I need to use the following streamlit cli command in a shell terminal to be able to see may page in a browser:

streamlit run my_st_page.py

or

python -m streamlit run my_st_page.py

Instead of running a shell command, how can I run the my_st_page page in my python program? What is the python module function call equivalent to streamlit run shell command above?

Thank you,
