Python中所有依赖于操作系统的内置模块的设计都是这样,只要不同的操作系统某一相同的功能可用,它就使用相同的接口。例如,函数 os.stat(path) 以相同的格式返回关于 path 的状态信息(该格式源于 POSIX 接口)。 特定于某一操作系统的扩展通过操作 os 模块也是可用的,但是使用它们当然是对可移植性的一种威胁。 所有...
Open a pipe to or fromcommand. The return value is an open file object connected to the pipe, which can be read or written depending on whethermodeis'r'(default) or'w'. Thebufsizeargument has the same meaning as the corresponding argument to the built-inopen()function. The exit status ...

system. It’s also a portable module, meaning you can use the same methods and get the same results whether you’re running your Python code on Windows, Mac OSX, or Linux so long as the os supports the functionality. If the operating system doesn’t support a method, an OSerror is ...
At the time of writing this version of Ubuntu does not have access to the Raspbian repositories, meaning that RPi.GPIO, the library needed to use the GPIO pins, is not available for use. But as Ubuntu for Raspberry Pi 2 is still in heavy development by the community it is just a matte...
On Unix, the return value is the exit status of the process encoded in the format specified for wait(). Note that POSIX does not specify the meaning of the return value of the C system() function, so the return value of the Python function is system-dependent. ...
