Python also has local variables. Local variables are defined inside of a function, and they only exist inside that function. The arguments given to a function are an example of local variables.You can read from global variables, as we did above in our see_message function. But can you ...
首先，global和local variable只是逻辑上的区分！技术上是一样，都是记录在collection里面，也就是你可以...

为了更好解决这个问题,python 线程库实现了 ThreadLocal 变量(很多语言都有类似的实现,比如Java)。ThreadLocal 真正做到了线程之间的数据隔离,并且使用时不需要手动获取自己的线程 ID,如下示例: global_data = threading.local() def show(): print threading.current_thread().getName(), global_data.num ...
