Cannot run updated file from terminal of VSC, for Python

So to make it very simple.

If I write print("Hello World") and run it on the RUN icon on top right corner it works perfectly fine.
And only then if I type in terminal python hello.py executes again just fine.

But if I change program to print("Hello to everybody") and I type in terminal python hello.py it executes the previous program and giving me Hello World on screen. But then again if I click on run icon and after correct execution repeat in terminal python hello.py, now it runs correctly.

Well I tried CTRL,SHift P, to change terminal and like select interpreter but couldn’t figure out from which file is it trying to start program. And why is it correct after I use run icon.
