append('..')之后search path加入了上级路径,在这里是package,包含p2,因此可以找到p2,再从p2里找到test2_function,fopen这一句报错有意为之,因为test.txt在p2里,而此时working directory仍然位于p1,p1里是没有"./test.txt"这个文件的,所以报错。这个报错是为了说明, sys.path和working directory是两个东西,wd既可...
Git stash stores the changes you made to the working directory locally (inside your project's .git directory;/.git/refs/stash, to be precise) and allows you to retrieve the changes when you need them. It's handy when you need to switch between contexts. It allows you to save changes t...

#模块可以包含可执行的语句和函数的定义,这些语句的目的是初始化模块,它们只在模块名第一次遇到导入import语句时才执行(import语句是可以在程序中的任意位置使用的,且针对同一个模块很import多次,为了防止你重复导入,python的优化手段是:第一次导入后就将模块名加载到内存了,后续的import语句仅是对已经加载到内存中的...

1.抽象函数/纯虚函数(pure virtual function) 抽象函数只有函数名、参数和返回值类型,不需要函数体,它的实现需要让子类去实现 2.抽象基类作用 · 处理继承问题方面更加规范、系统 · 明确调用之间的相互关系 · 使得继承层次更加清晰 · 限定子类实现的方法 ...
While all new process are created with the same system calls, the context from which the system call is made is different. The run() function can make a system call directly and doesn’t need to go through the shell to do so:In fact, many programs that are thought of as shell ...
