Question

I want to write a script which will do some specific job, each time when the job is done, I want to increase a job_done_count by 1, that is if I run the script 10 times, job_done_count will be 10.

This is how this script looks like,

#!/usr/bin/env python

job_done_count = 0   
...

if __name__ == '__main__':
    do_the_job()
    job_done_count += 1

I kind wonder it works or not. Because, each time I run the script, job_done_count will be set to 0, then 1. It doesn’t remember how many times the job being done at all.

Am I supposed not to put this job_done_count in the script?

Answer 1

Or don’t use pickle and do it in any of the following ways.

By hand

with open("jobs_done.txt") as inp:
    job_done_count = int(inp.read().strip())

With json

with open("jobs_done.json") as inp:
    job_done_count = json.load(inp)['jobs_done']

Or with a billion other methods!
