在Python中有可能发生这种情况吗？

Question

I have an executable file (hello.exe) that was given to me by a friend. This executable file creates another exe file (test.exe) and runs the executable through another command line window. I wanted to was attempting to write a script that ran hello.exe, and grabbed the output of test.exe. I'm very new to python and am familiar with system calls and redirecting output, but this is a special case because I am not directly accessing test.exe. Another problem I am facing is that hello.exe waits for a keyboard response from test.exe before doing anything else. Is it possible for me to run my hello.exe script and grab the output from test.exe in the same script?

import sys, string, os

os.system(hello.exe) > "test.txt" //Something like this?? Grab output from test.exe and put in test.txt
print "test" //this doesn't print until keystroke from terminal running test.exe

Answer 1

perhaps

os.system("hello.exe > test.txt")

alternatively

subprocess.Popen("hello.exe",stdout=open("test.txt","w")).communicate("\n")
