print(help(subprocess.call))"""Help on function call in module subprocess:call(*popenargs, timeout=None, **kwargs) Run command with arguments. Wait for command to complete or timeout, then return the returncode attribute. The arguments are the same as for the Popen constructor. Example: re...
status = subprocess.call("mycmd" + " myarg", shell=True) Notes: Calling the program through the shell is usually not required. A more realistic example would look like this: try: retcode = call("mycmd" + " myarg", shell=True) if retcode < 0: print >>sys.stderr, "Child was te...

我们可以通过 create_subprocess_exec() 函数从 asyncio 程序执行命令。 asyncio.create_subprocess_exec() 函数接受一个命令并直接执行它。 这很有用,因为它允许命令在子进程中执行,并允许 asyncio 协程读取、写入和等待它。 与asyncio.create_subprocess_shell() 函数不同,asyncio.create_subprocess_exec() 不会使用...
process = await asyncio.create_subprocess_exec('ls') 正在执行的命令的参数必须作为后续参数提供给 create_subprocess_exec() 函数。 ... # execute a command with arguments in a subprocess process = await asyncio.create_subprocess_exec('ls', '-l') ...
This example is largely the same as the one introduced in the first section: we are still running a subprocess to printocean. Importantly, however, we pass thecapture_output=Trueandtext=Truekeyword arguments tosubprocess.run. subprocess.runreturns asubprocess.CompletedProcessobject that is bound ...
The Python subprocess module is used to run shell commands and manage external processes. You run a shell command using subprocess by calling subprocess.run() with the command as a list of arguments. subprocess.call(), subprocess.run(), and subprocess.Popen() differ in how they execute ...
