python: Importing modules in project using dynamic naming

Question

My project layout looks like:

run.py
jobs/
   job1.py
   job2.py

job1.py is pretty basic:

class job1():

    def __init__(self):
        print 'yo'

In run.py, I have:

name = 'job1'
classname = 'jobs.%s' % name
__import__(classname)

Which obviously does not work:

Traceback (most recent call last):
  File "run.py", line 5, in <module>
    __import__(classname)
ImportError: No module named jobs.job1

What is the best way to import the modules in this manner?

So I can easily add the modules by putting their classes in the jobs directory. — Wells

This is very similar to Dynamic module import in Python. And as Ashwini Chaudhary explains below, you are probably simply missing an __init__.py file in your jobs folder to make it a package. — Rodrigue

first of all create a __init__.py file inside jobs folder, to make this jobs.jobs1 thing work.

Add this to your __init__.py in jobs directory

import os
jobs = {}
for module in (name for name in os.listdir(".") if name.endswith(".py")):
    jobs[module] = __import__(module)

Then just use it like this

from jobs import jobs
