python重置变量 sys.defaultencoding

<font color="#000099"><strong><span style="font-size:24px;">例如重置变量<span style="font-family:Arial;line-height: 25.99px; font-size: 13.63px;"> </span><span class="hilite1" style="font-family:Arial;line-height: 25.99px; font-size: 13.63px;"><span style="background-color: rgb(255, 255, 0);">sys</span></span><span style="font-family:Arial;line-height: 25.99px; font-size: 13.63px;">.defaultencoding <span style="font-size:24px;">为utf-8</span></span></span></strong></font>

<pre class="python" name="code"><span style="font-size:18px;">#-*- coding:utf-8 -*-
import sys
reload(sys)
sys.setdefaultencoding('utf-8')</span>

<span style="font-size:24px;color:#000099;"><strong>但是如下代码在pycharm里能正常输出，在windows里直接运行.py文件就乱码</strong></span>

#-*- coding:utf-8 -*-
import sys
reload(sys)
sys.setdefaultencoding('utf-8')

num_1=float(raw_input(u'来一个数：\n'))
num_2=float(raw_input(u'再来一个数：\n'))
result=num_1+num_2
print 'result is',result

windows命令行环境下只正确显示 GBK/GB2312编码
如果要正常显示要这样写： number = raw_input(u‘我是谁‘.encode(‘gbk‘))

 改成

#-*- coding:utf-8 -*-
import sys
reload(sys)
sys.setdefaultencoding('utf-8')

num_1=float(raw_input(u'来一个数：\n'.encode('gbk')))
num_2=float(raw_input(u'再来一个数：\n'.encode('gbk')))
result=num_1+num_2
print 'result is',result
