The function prints the time and then return `0`. Try `a = os.system('date')` You won't see the zero now. Now check the value of a and you will find it `0`. – Jithin Pavithran Oct 02 '16 at 14:07

Thats the exit status of the program, 0 normally means the program finished without error.

You are performing a system call. 0 is the return code of this call. If you are trying to just get the current time use: datetime.datetime.now()
