  1. 一般情况下，一个函数结束的时候，加一个return在代码上比较美观。可以更清楚的知道代码在哪里结束。 

    虽然不加也可以，但是建议加上。这样可以更清楚的知道代码在哪里结束。如果您用过try...except...else...finily结构的话，会明白的

  1. python中的闭包 for python 3.x 

    UnboundLocalError: local variable 'count' referenced before assignment.

什么意思?就是说conut这个变量你没有定义就直接引用了,我不知道这是个什么东西,程序就崩溃了.于是,再python3里面,引入了一个关键字:nonlocal,这个关键字是干什么的?就是告诉python程序,我的这个count变量是再外部定义的,你去外面找吧.然后python就去外层函数找,然后就找到了count=0这个定义和赋值,程序就能正常执行了.
