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...
如果不加check=True,程序出错了也不会报错,只能从#stderr里面看a = subprocess.run(['df','-h'], stderr=subprocess.PIPE, stdout=subprocess.PIPE, check=True)print(a.stdout)#拿到结果print(a.returncode)#0 0代表命令执行成功print(a.check_returncode())#如果用到管道命令,直接写成一个字符串就行,...
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...
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 ...
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 ...
Python的Subprocess模块的subprocess.run(args, *,...)形参？这里是一个省略写法，subprocess.run与 subprocess.Popen 的大部分参数一致，因此只列出最常用的参数 +subprocess.run特有参数。The arguments shown above are merely the most common ones, described below inFrequently Used Arguments(hence the use of ...
