Python中文显示问题

默认pyhon使用ASCII码来解释程序的，默认不支持中文，需要在程序的第一行或者第二行声明编码。

官方解决方案：https://www.python.org/dev/peps/pep-0263/

    To define a source code encoding, a magic comment must
    be placed into the source files either as first or second
    line in the file, such as:

          # coding=<encoding name>

    or (using formats recognized by popular editors)

          #!/usr/bin/python
          # -*- coding: <encoding name> -*-

    or

          #!/usr/bin/python
          # vim: set fileencoding=<encoding name> :
