使用Python子进程和字符串格式化(Using Python subprocess and string formating)

 我试图使用python的subprocess调用带有相关参数的windows命令。 命令正在执行，参数及其值看起来是正确的，但是当使用“本地模式” -l时，它似乎只能正常工作。 使用远程模式时，我收到invalid argument/option错误。 可以指出哪里出错？ 
 
 任何人都可以指出如何正确格式化subprocess.check_ouput()参数以包含执行脚本时在命令行中给出的变量？ 正如你所看到的，我尝试使用字符串格式化，无论是新旧还是尝试让它工作，因为我无法锻炼如何在过滤器（/ FI）参数值之间添加最后一个domain变量而没有字符串格式。 
 
 预期的命令行执行 
 
tasklist /V /S 192.168.1.122 /U 'DOMAIN'\'USERNAME' /P 'PASSWORD' /FI "USERNAME eq 'DOMAIN'\*"
 
 使用此命令行脚本示例： 
 
hunter.py -d DOMAIN -u USERNAME -p PASSWORD -s servers.txt
 
 这是错误： 
 
ERROR: Invalid argument/option - '/S 192.168.1.122'.
Type "TASKLIST /?" for usage.
 
 显然，论证无论如何都是正确的“视觉上”正确，这里是任务列表的用法： 
 
Description:
This tool displays a list of currently running processes on
either a local or remote machine.

Parameter List:
/S     system           Specifies the remote system to connect to.

/U     [domain\]user    Specifies the user context under which
                       the command should execute.

/P     [password]       Specifies the password for the given
                       user context. Prompts for input if omitted.

/M     [module]         Lists all tasks currently using the given
                        exe/dll name. If the module name is not
                        specified all loaded modules are displayed.

/SVC                    Displays services hosted in each process.

/APPS                   Displays Store Apps and their accociated processes.

/V                      Displays verbose task information.

/FI    filter           Displays a set of tasks that match a
                        given criteria specified by the filter.

/FO    format           Specifies the output format.
                        Valid values: "TABLE", "LIST", "CSV".

/NH                     Specifies that the "Column Header" should
                        not be displayed in the output.
                        Valid only for "TABLE" and "CSV" formats.
/?                      Displays this help message.
 
 这是我到目前为止的python 代码 ;

I am attempting to call a windows command with relevant arguments using python's subprocess . The command is executing and the arguments and their values look to be correct, however It only seems to be working correctly when using the "local mode" -l. I'm getting an invalid argument/option error when using the remote mode. Could any point out where im going wrong?
 
Could anyone point out how to format the subprocess.check_ouput() arguments correctly to include the variables given at commandline when executing the script? As you can see ive tryd using string formating, both old and new to try get it working as I cant workout how to add the last domain variable inbetween the filter (/FI) argument value without string formatting.
 
expected commandline to execute
 
tasklist /V /S 192.168.1.122 /U 'DOMAIN'\'USERNAME' /P 'PASSWORD' /FI "USERNAME eq 'DOMAIN'\*"
 
with this commandline example of the script:
 
hunter.py -d DOMAIN -u USERNAME -p PASSWORD -s servers.txt
 
This is the error:
 
ERROR: Invalid argument/option - '/S 192.168.1.122'.
Type "TASKLIST /?" for usage.
 
Clearly the argument is correct "visually" correct anyway, here is the usage for the tasklist:
