check: 如果check参数的值是True,且执行命令的进程以非0状态码退出,则会抛出一个CalledProcessError的异常,且该异常对象会包含 参数、退出状态码、以及stdout和stderr(如果它们有被捕获的话)。 stdout, stderr:input: 该参数是传递给Popen.communicate(),通常该参数的值必须是一个字节序列,如果universal_newlines=Tru...

You can pass many options to the configure script; run./configure --helpto find out more. On macOS case-insensitive file systems and on Cygwin, the executable is calledpython.exe; elsewhere it's justpython. Building a complete Python installation requires the use of various additional third-pa...
st_size: size of file in bytes st_atime: time of last access st_mtime: time of last modification st_ctime: time of last metadata change on Unix, or time of creation on Windows You can then use this data with thestatmodule to get interesting information, like whether a path points to...
