To copy a whole folder with all non-code files, you can use --include-data-dir=/path/to/images=images which will place those in the destination, and if you want to use the --noinclude-data-files option to remove them. Code files are as detailed above DLLs, executables, Python files,...

上下文管理器对象存在以控制with语句,就像迭代器存在以控制for语句一样。 with语句旨在简化一些常见的try/finally用法,它保证在代码块结束后执行某些操作,即使代码块由return、异常或sys.exit()调用终止。finally子句中的代码通常释放关键资源或恢复一些临时更改的先前状态。
User-defined exceptions: Custom exceptions are those that you create when no built-in exception fits your needs. You’ll typically put them in a dedicated module for a specific project. In the following sections, you’ll find some guidelines for deciding which exception to raise in your code....
