import subprocess
import sys
proc = subprocess.Popen(["program.exe"], stdin=subprocess.PIPE) #the cmd program opens
proc.communicate(input="filename.txt") #here the filename should be entered (runs)
#then the program asks to enter a number:
proc.communicate(input="1") #(the cmd stops here and nothing is passed)
proc.communicate(input="2") # (same not passing anything)
我如何使用 python 传递和与 cmd 通信。
谢谢。(使用windows平台)
