Note that the root directory will not change if you then run code from another file unless you interrupt/restart the kernel (or close VS Code). On this aspect, see the following comment and the corresponding github issue. For the Python Interactive Window, the setting you're looking for is...
现在,如果您点击 步入(I) 按钮 ,您将看到调试器进入文件 parse.py : 然而,如果您继续使用 ,您会看到您的应用程序直接进入下一个循环: 如果您想专注于自己的代码,请使用 单步执行我的代码 按钮。 这样,您就可以避免进入库类。 有关更多信息,请参阅 单步调试工具栏和逐步执行程序。 监视 PyCharm 允许您监...

我们发现我们明智地分层的架构已经像过于湿润的杂果布丁一样崩溃了。混乱的软件系统的特征是功能的相同性:具有领域知识并发送电子邮件和执行日志记录的API处理程序;“业务逻辑”类不进行计算但执行 I/O;以及一切与一切耦合,以至于改变系统的任何部分都充满了危险。这是如此普遍,以至于软件工程师有自己的术语来描述混乱:...
sendfile(2) is a UNIX system call which provides a “zero-copy” way of copying data from one file descriptor (a file) to another (a socket). Because this copying is done entirely within the kernel, sendfile(2) is more efficient than the combination of “file.read()” and “socket....
