How to divide by time Python

Question

I want my program to calculate how many jobs it completes per minute.

Here is what the program already knows:

ORIGINAL_NUM_OF_TOTAL_JOBS = this is the number of jobs it was told to complete NUM_OF_TOTAL_JOBS_REMAINING = This is the number of jobs remaining

 print "\nTime Elapsed:" 
            TIME_ELAPSED = datetime.now() - STARTTIME
            print TIME_ELAPSED
            JOBS_PER_MINUTE = ORIGINAL_NUM_OF_TOTAL_JOBS - NUM_OF_TOTAL_JOB_REMAINING / TIME_ELAPSED
            print "\nAttempts/minute: "
            print JOBS_PER_MINUTE

I know the logic isn't right above because I'm dividing by "time" and time doesnt neccessarily = per minute, but im stuck.

Output/Error Message from python

Time Elapsed:
0:00:00.146000
Traceback (most recent call last):

    ATTEMPTS_PER_MINUTE = ORIGINAL_NUM_OF_TOTAL_ATTEMPTS - NUM_OF_TOTAL_ATTEMPTS / TIME_ELAPSED
TypeError: unsupported operand type(s) for /: 'int' and 'datetime.timedelta'

Answer 1

TIME_ELAPSED is a datetime.timedelta object ( https://docs.python.org/2/library/datetime.html#datetime.timedelta ). It has the method total_seconds() . Divide that by 60 to get the time elapsed in minutes.

TIME_ELAPSED = datetime.now() - STARTTIME
minutes = TIME_ELAPSED.total_seconds() / 60.0
ATTEMPTS_PER_MINUTE = (ORIGINAL_NUM_OF_TOTAL_ATTEMPTS - NUM_OF_TOTAL_ATTEMPTS) / minutes
