我有外部脚本(sh),我想做这样的事情:
arg1 = 'some string'
arg2 = 'some string2'
arg3 = ''
cmd = ['/usr/local/bin/myscript', 'arg1', 'arg2', 'arg3']
Popen(cmd, shell=False, stdin=PIPE, stdout=PIPE, stderr=PIPE)
我看来,如果“arg3”为空,我的脚本只用两个参数调用, 如果它是空的,我怎么能传递“arg3”事件?

test.py:
import sys
print(sys.argv)
test2.py:
import subprocess
import shlex
cmd="test.py 'some string' 'some string2' '' "
proc=subprocess.Popen(shlex.split(cmd))
运行test2.py产生
['test.py', 'some string', 'some string2', '']

Popen(cmd[0] + [ repr(x) for x in cmd[1:]],
shell=False,
stdin=PIPE,
stdout=PIPE,
stderr=PIPE)
