I suggest you create a new folder at this path called as you wish, and then create this file there.
import sublime, sublime_plugin
class HelloWorldCommand(sublime_plugin.TextCommand):
def run(self, edit):
self.view.insert(edit, 0, "Hello World")
#TO RUN THIS FILE:
# 1.Open the Console
# 2.Digit: `view.run_command('hello_world')`
