[英]Send commands to cmd prompt using Python subprocess module
using python 3.7使用 python 3.7
I have the following issue: I wrote a python script in which I open a cmd prompt, do some actions then I want to send some commands to that opened cmd prompt我有以下问题:我写了一个 python 脚本,在其中打开 cmd 提示符,执行一些操作然后我想向打开的 cmd 提示符发送一些命令
To simplify, it looks something like:为了简化,它看起来像:
import subprocess
process = subprocess.Popen(['start','cmd','/k','dir'], shell = True, stdin= subprocess.PIPE,
stdout = subprocess.PIPE, text = True)
"DO some actions"
input = 'date'
process.stdin.write(input)
process.communicate(input, timeout = 10)
All the time the script exits with exception TimeoutExpired, and in the cmd prompt i do not see command written (the input)脚本一直退出并出现 TimeoutExpired 异常,并且在 cmd 提示符下我没有看到写入的命令(输入)
I looked in the documentation, but i am new with python and did not understood very well how to use the subprocess module我查看了文档,但我是 python 的新手,不太了解如何使用子流程模块
Thank you for the support!谢谢你的支持!
