read and right a text file through batch in python Answered

Ok so I have a
- batch file named run.choice.bat 
- text file named choice.txt
- text file named python.txt
- and a python file named choice.py

The batch file contains this code:
@echo off
set /p c=<"choice.txt"
echo %c%
choice /c:%c%
echo %errorlevel%
echo %errorlevel% > python.txt
pause

The python file contains this code:
def choice(keys="yn"):
    """Choice.com"""
    import os
    import time
    o = open("choice.txt", "wb")
    o.write(keys);
    time.sleep(1)
    os.system("run.choice.bat")
    i = open("python.txt", "r+")
    errorlevel=int(i.read(2))
    return errorlevel
choice(raw_input("choice("))

my problem is that the batch file wont read choice.txt while running in python, on its own it runs fine.
can somebody help me fix it?
