问题描述

我有一个外部可执行文件，我试图从 Python 脚本运行它.CMD 可执行文件运行但不生成输出.可能它在生成输出之前退出.关于如何延迟退出直到生成输出的任何建议?

I have an external executable file which I am trying to run from a Python script. CMD executable runs but without generating output. Probably it exit before output can be generated. Any suggestion about how to delay exit until outputs are generated?

import subprocess, sys
from subprocess import Popen, PIPE
exe_str = r"C:/Windows/System32/cmd C:/temp/calc.exe"

parent = subprocess.Popen(exe_str, stderr=subprocess.PIPE)

解决方案

使用 subprocess.call，更多信息 这里:

import subprocess
subprocess.call(["C:\temp\calc.exe"])

或

import os
os.system('"C:/Windows/System32/notepad.exe"')

希望对你有帮助……
