[Tutor] Executing a command from a specific directory

[Ansuman Dash]

Hi,

I modified my code little bit and it is working fine now,

=====================================================
    if os.access("C:/Python25/Own.log", os.F_OK):
        f = open("C:/Python25/Own.log")
        time.sleep(30)
        try:
            line = f.readlines()
            a = string.join(line)

            if "Request timed out.." not in a:
                print("Ping is not successful.")
                pLogger.info("Ping is not successful.")
            else:
                print ("Ping is successful.")
                pLogger.info("Ping is successful.")

        finally:
            f.close()
    else:
        pLogger.info("File doesn't exist")
=======================================================

But I have question to ask, as you can see I am using "time.sleep(30)" to
make my code wait. Is there any other way I can write my script to resolve
synchronization issues.

Thanks,
AD
