It sounds like "hello.py" is the name of the file that contains your code. If you don't also have a file named "hello_world.py", then telling Python to start a file with that name won't do anything.

Regardless of the file name what happens when you run it depends on the code inside the file.

if you want to print the same output hello world, using python hello_world.py command, change the filename hello.py to hello_world.py. Hope this helps.
