Python Web Development Techdegree Student 38,319 PointsBecause the file is named hello.py, and for the hello_world.py to work you would need a file named hello_world.py

216,017 PointsIt 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.
