A new tab doesn't open up in my web-browser if I run the streamlit-python script

I usually use the python IDLE. I also tend to run from the IDLE by pressing the F5. My usual way of running python script didn’t work. Can you please tell me how to run this from terminal ? I tried once, but didn’t work from terminal. My file is in the J:/ drive , in st folder.

Can you please give the exact command or way to run the code from the terminal ?
