Python：如何编写代码，使其能自动在cmd中输入？

Posted 2023-04-06

举例：首先有一个在cmd中运行的小程序，假设为"apple.cmd"，然后os.system('apple.cmd'),此时弹出了该程序在cmd上的运行过程。但由于中间该程序因某种原因(如未找到‘xxx文件’)，显示“是否继续Y/N”，需要按Y 才能继续执行，该如何去处理这个按Y的动作？

参考技术A 类似这样，
from subprocess import Popen, PIPE, STDOUT
p = Popen(['myapp'], stdout=PIPE, stdin=PIPE, stderr=PIPE)stdout_data = p.communicate(input='data_to_write')[0]

但是你需要同时监控stdout以便确定输入的时机（自己查，也可以帮写）本回答被提问者和网友采纳 参考技术B 加个异常处理，try，exception
如果遇到异常，自动输入“Y”
希望我的回答对你有帮助，你的采纳就是最好的鼓励~追问

不是异常，是流程的一部分，举例说：工具未找到‘xx文件’，是否继续Y/N？是这类问题

修改汇编语言程序，添加功能 使其能完成以下功能

1）输入带符号十进制，转换成十六进制补码显示。
1）输入十六进制补码，转换成带符号十进制真值显示。

急用，改好的万分感谢，请私信给我。。。又追加。。

参考技术A 你匿名无法私信，增加了2个新函数INDECS OUTDECS,大多在原函数上改的,改的地方有';'.
