Python appears syntaxerror:non-ascii character ' \xe6 ' in file print date. py on line 1, but no encoding declared;

Just beginning to learn python, read the book on the Code:

#根据给定的年月日以数字的形式打印出来
months = [
     ' January ',
     ' febuary ', '
     March ',
     ' April ',
     ' may ',
     ' June ' ,
     ' July ',
     ' August ',
     ' September ',
     ' October ',
     ' November ',
     ' December '
]

The 1~31 number as the end of the list
endings = [' st ', ' nd ', ' Rd '] + * [' th '] \
        + [' st ', ' nd ', ' Rd '] + 7 * [' th '] +
        [' st ']
  year    = Raw_input (' year: ')
Month   = Raw_input (' Month (1-12): ')
Day     = raw_input (' Day ' ( 1-31) '

month_number = Int (month)
day_number = Int (day)

#记得要将月份和天数减1 to get the correct index
month_name = MONTHS[MONTH_NUMBER-1]
ordinal = day + endings[day_number-1]

print Month_name + ' + ordinal + ', ' + year
  
   ~                                           
  

An error occurred while executing:

Syntaxerror:non-ascii character ' \xe6 ' in file print date. py on line 1, but no encoding declared; Http://www.python.org/peps/pep-0263.html for details

Baidu a bit:

The discovery is because Python does not support encoding in the source file in the default state. The solutions are as follows: three

First, add the following annotation code to the head of the file:

# coding=<encoding Name> For example, you can add a # Coding=utf-8

Second, add the following two lines of comment code to the head of the file:

#!/usr/bin/python

#-*-Coding: <encoding name>-*-For example, you can add #-*-Coding:utf-8-*-

Third, add the following two lines of comment code to the head of the file:

#!/usr/bin/python

# Vim:set fileencoding=<encoding name>: For example, you can add a # Vim:set Fileencoding=utf-8:

I used the first method to solve it. Record it.
