1. When Python hello.py, it is clear that the hello.py script is executed by the Python interpreter.
2. If you want to execute a python script like executing a shell script, for example:./hello.py, then you need to specify the interpreter in the header of the hello.py file, such as:

   1 # !/usr/bin/env python 2 Print " Hello,world " 3 # Note: Need to give hello.py execution permission before execution, chmod 755 hello.py

3. In addition to writing the program in the file, you can also call the Python's own interactive running code directly. (Not recommended)
