在windows10下搭建Python3的开发环境：
1.下载Anaconda3，下载地址百度，根据自己的windows环境下载32-bit或者64-bit
2.安装Anaconda3，选择完安装路径之后，在第二步骤的时候，有两个选项：如图
第一个选项是添加系统path环境变量，第二个将Python3.6作为idea的默认开发环境，两个都打勾。
3.安装完成之后配置pycharm的环境,如图：
3.配置好之后在cmd输入Python之后，如图，表示python的环境配置成功：
下面就可以开发Python了。
关于Python3.6与Anaconda3的区别自行百度
4.flask是Python开发的web框架，与Java的spring框架是一个道理。如何使用flask,它的api:
http://docs.jinkan.org/docs/flask/
下面是一个简单的flask的web程序
server.py
from gevent.wsgi import WSGIServer
from tornado.httpserver import HTTPServer
from SnowNLP_JS import app（这段代码是引入了SnowNLP_JS.py 作为一个app的变量）
http_server = WSGIServer(('127.0.0.1', 5000), app)
http_server.serve_forever()

以上的方法实现了情感词分析的功能。同时实现了跨域的问题。
5.请求方式
http://127.0.0.1:5000/getfunc
参数：json格式的数据，{content:"你好！"}
6.如果出现模块不存在后者是未定义的错误，需要安装该模块，命令：
pip install 模块名
