os.walk()

这个函数yield一个3-tuple(dirpath, dirnames, filenames) 解释 dirnames is a list of the names of the subdirectories in dirpath (excluding ‘.’ and ‘..’). filenames is a list of the names of the non-directory files in dirpath. Note that the names in the lists contain no path components. To get a full path (which begins with top) to a file or directory in dirpath, do os.path.join(dirpath, name).

os.getcwd()

或者linux里面的pwd命令 和os.path.dirname()的区别 起因为binscope会在当前工作目录下产生一个log，而我要把这个删掉，但是我起初没有当前工作目录的概念。 工作目录并不是当前文件所在的目录—这点要注意

获取根目录下的文件和目录的绝对路径

[os.path.join(‘/’, path) for path in os.listdir(‘/’)]

获取绝对路径

os.path.abspath(__file__)

进程相关os

os.execv(path, arglist) 取代当前的进程 Execute an executable path with arguments, replacing current process. path: path of executable file args: tuple or list of strings os.getpid() 当前的进程pid
