python解决中文编码问题

程序中出现中文,运行的时候出现如下错误:

 

SyntaxError: Non-UTF-8 code starting with '\xb1' in file rate.py on line 5, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

 

导致出错的根源就是编码问题。

解决方案是:

     在程序最上面加上:# coding=gbk

这样程序就可以正常运行了。

 

eg1:

 

#!/usr/bin/python
#-*- coding:GBK -*-

 

principal = 1000 # Initial amount (本金)
rate = 0.05 # Interest rate (利率)
numyears = 5 # Number of years (期数,年)
year = 1

 

while year <= numyears:
        principal = principal*(1+rate)
        print (year, principal)
        year += 1

 

 

eg2:

 

#!/usr/bi/python
#-*- coding:GBK -*-

s1=input('Input your name:')
print('你好,%s' % s1)
