如何从python子进程执行netcat命令？

Question

我需要通过python脚本执行Altair Accelerator，以前称为NetworkComputer (NC)。我的外壳命令是：nc run -q vnc01 run -C TEST -wl -I -r+ CORES/32 -r+ RAM/150000 -- /bin/tcsh我试过这个代码：

with open('test.txt', 'w') as f:
    process = subprocess.Popen(['nc run',' -q vnc01  run -C TEST -wl -I -r+ CORES/32 -r+ RAM/150000 -- /bin/tcsh'], stdout=f)

返回以下错误：

Traceback (most recent call last):   File "nc.py", line 11, in <module>
    process = subprocess.Popen(['nc run',' -q vnc01 run -C TEST -wl -I -r+ CORES/32 -r+ RAM/150000 -- /bin/tcsh'], stdout=f)   File "/usr/lib64/python2.7/subprocess.py", line 711, in __init__
    errread, errwrite)   File "/usr/lib64/python2.7/subprocess.py", line 1327, in _execute_child
    raise child_exception OSError: [Errno 2] No such file or directory Exit 1

您需要正确地拆分命令参数：

process = subprocess.Popen([
    'nc',
    'run', '-q', 'vnc01',
    'run', '-C', 'TEST',
    '-wl', '-I',
    '-r+', 'CORES/32',
    '-r+', 'RAM/150000',
    '--',
    '/bin/tcsh'
], stdout=f)
