传入命令参数时,需要以多个命令拆分按照列表形式传入:subprocess.run(['df', '-h'], stdout=subprocess.PIPE, stderr=subprocess.PIPE, check=True) 如果传入参数同时传入shell=True,则传入一个字符串args,shell命令而不是待执行的shell命令序列 实例: >>> subprocess.run(["ls","-l"])#doesn't capture out...
Run command with arguments and return its output.If the exit code was non-zero it raises a CalledProcessError. TheCalledProcessError object will have the return code in the returncodeattribute and output in the output attribute.执行命令,如果状态码是0,则返回执行结果,否则抛出异常--subprocess.check...
CompletedProcessObject=subprocess.run(args=str_shell,shell=True,stdin=subprocess.PIPE,stdout=subprocess.PIPE, stderr=subprocess.PIPE,universal_newlines=True,timeout=10,check=False) if CompletedProcessObject: code,out,err=CompletedProcessObject.returncode,CompletedProcessObject.stdout,CompletedProcessObject.stderr...
subprocess.run() 模块可供参考的初学者教程:https://www.dataquest.io/blog/python-subprocess/ run(*popenargs, input=None, capture_output=False, timeout=None, check=False, **kwargs) # 带参数运行命令, 并返回一个 CompletedProcess 实例. Run command with arguments and return a CompletedProcess instanc...
subprocess.run() 运行并等待args参数指定的指令完成,返回CompletedProcess实例。 参数:(*popenargs, input=None, capture_output=False, timeout=None, check=False, **kwargs)。除input, capture_output, timeout, check,其他参数与Popen构造器参数一致。

2.2:subprocess.check_call 与subprocess.call功能一样,不过在命令退出状态不为0时,raise CalledProcessError(retcode, cmd) print(help(subprocess.check_call)) """check_call(*popenargs, **kwargs) Run command with arguments. Wait for command to complete. If the exit code was zero then return, otherw...
subprocess.run（）⽤法python3.7 def run(*popenargs,input=None, capture_output=False, timeout=None, check=False, **kwargs):"""Run command with arguments and return a CompletedProcess instance.The returned instance will have attributes args, returncode, stdout and stderr. By default, stdout ...
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 ...
