解决方案

环境：python2.7

百度下，只有几个例子，有个说是某个函数被重新定义了，导致出问题。
我仔细看了下我的错误：
Traceback (most recent call last):
? File "/usr/local/lib/python2.7/dist-packages/eventlet-0.14.0-py2.7.egg/eventlet/hubs/hub.py", lin......
答案就在这里：TypeError: 'tuple' object is not callable

解决方案二：

你len访问的对象，它没有个数的概念。不能获取它的长度等。只有list等对象有len
