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...
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...

'-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,不用列表,还要加上shell=True,告诉run方法你不要解析了,因为有管道你也处理不了,把整个命令...
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 ...
2.1:subprocess.call 看下面的解释:与os.system()功能是一样; 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 argum...
python3.5版本前,call(), check_all(), checkoutput()三种方法构成了subprocess模块的高级API。 subprocess.call() 运行并等待args参数指定的指令完成,返回执行状态码(Popen实例的returncode属性)。 参数:(*popenargs, timeout=None, **kwargs)。与Popen构造器参数基本相同,除timeout外的所有参数都将传递给Popen接口...
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...
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') ...
