也就是说在每个py 中进行的import 动作并不会影响上一层的名字空间,只是影响各个module 自身的名字空间;但所有import 动作,无论发生在什么时间、什么地点,都会影响到全局module 集合即 sys.modules。图中的 __file__ 是文件路径名。 注意:尽量避免相互引用,这是模块化开发的一条准则。
During handling of the above exception, another exception occurred: 它的意思是:在处理上述异常期间,发生了另一个异常。简单理解就是在 except 中的代码出现了异常。所以导致了这种现象。这个例子就是在第三次循环的时候 person=1 然后字符串 hi 和1 不能进行拼接操作,然后再次引发了异常。查看所有的错误信息输...

而其他阻塞是指调用time.sleep()、anotherthread.join()或等待IO时的阻塞,这个状态下线程不会释放已获得的锁定。 tips: 如果能理解这些内容,接下来的主题将是非常轻松的;并且,这些内容在大部分流行的编程语言里都是一样的。(意思就是非看懂不可 >_< 嫌作者水平低找别人的教程也要看懂) ...
