Python的contextlib模块引入了一种编写上下文管理器的方式,可用于创建带有“with”语句的装饰器。例如,我们可以创建一个上下文管理装饰器用于自动关闭文件: from contextlib import contextmanager @contextmanager def auto_close(file_obj): try: yield file_obj finally: file_obj.close() @auto_close def read_fi...
有了PyTryBlock存储一系列栈上信息,就可以保证 with结构下的代码块在结束之后,整个栈上的状态能够恢复到 with之前的状态。注意这个时候栈顶上是 __exit__函数,这样如果之后恢复栈,然后push一系列错误信息,我们的 __exit__函数就能处理对应的错误信息了。 BlockSetup之后,就是把 __enter__的返回值推进栈里,交由...
