python脚本打开Windows命令提示符并打印一些字符串

Question

I have a scenario where I have 3 python script files . Using one file I will create a text file. Using the other two script files, I will append some strings to the file which I have created earlier. So far, it's working good.

But, I need to do the same in a different way now. I need to open a command prompt , then print the strings on that command prompt, using two python script files.

Can anyone please help?

Thanks in Advance.

I'm guessing that you're using windows so I'll attempt to answer your question with that assumption. If I understand what you're trying to accomplish you have 1 script to launch the command prompt, then you want to launch the other 2 scripts and redirect output to the command line. Because you're really light on the details all I can give you is some pretty generic stuff with the easy way being something like this:

import subprocess
# Opens cmd.exe and pipes stdout
p1 = subprocess.Popen('cmd', shell=True, stdin=None, stdout=subprocess.PIPE)

# Runs python scripts using stdin and stdout from p1
p2 = subprocess.Popen('python.exe foo.py', shell=True, stdin=p1.stdout)
p3 = subprocess.Popen('python.exe bar.py', shell=True, stdin=p1.stdout)
p1.stdout.close()
p2.communicate()
p3.communicate()

Another option would be to allow arguments so you would run the initial script like this:

python main.py foo.py bar.py

Without a more specific question that's about as good an answer as I can come up with.
