Python运行外部executab

Question

我正在尝试运行一个外部可执行文件，它需要复杂的参数并将输出捕获到一个变量中。我该怎么做

import os
import subprocess
subprocess.call('C:\\bin\\test.exe', ' -b10.10.2000',' -house50.20E,10.40N',' -hsyE',' -utc00.18',' -eswe',' -sid27',' -fPls',' -head',' -g')


>>> subprocess.call('C:\\bin\\test.exe', ' -b10.10.2000',' -house50.20E,10.40N',' -hsyE',' -utc00.18',' -eswe',' -sid27',' -fPls',' -head',' -g')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\user\AppData\Local\Programs\Python\Python38\lib\subprocess.py", line 3
25, in call
    with Popen(*popenargs, **kwargs) as p:
  File "C:\Users\user\AppData\Local\Programs\Python\Python38\lib\subprocess.py", line 7
29, in __init__
    raise TypeError("bufsize must be an integer")
TypeError: bufsize must be an integer
>>>

谢谢

输出是另一个进程的标准输出

可以使用subprocess.Popen和communicate（），然后：

 proc = subprocess.Popen( [ 'C:\\bin\\test.exe', '-b10.10.2000','-house50.20E,10.40N','-hsyE','-utc00.18','-eswe','-sid27','-fPls','-head','-g' ], stdout = subprocess.PIPE, stderr = subprocess.PIPE )
 out, err = proc.communicate() #out -> stdout, err -> stderr
