控制台打印乱码：
print '你好，世界！'.decode('utf-8')
url = 'http://{0}:{1}/{2}'.format('0.0.0.0', 2375, 'xxx')
url = 'http://{ip}:{port}/{uri}'.format(ip='0.0.0.0', port=2375, uri='xxx')
url = 'http://%s:%d/%s' % ('0.0.0.0', 2375, 'xxx')whl 包下载pip install *.whl 或者修改.whl文件为.zip文件，解压缩文件的Python文件夹复制到--python安装目录下的Lib--目录下假如
sys.path不对,则使用Python终端sys.path = [...]重新设置即可. 默认环境配置如下：
