I don't think dealing with a specific API is actually appropriate for
this list. I'll try to answer the general elements.

First question: Why do you need multiple versions of this theoretical
class floating around? Perhaps if you wrote a single module api that
handles interactions with the API, you can then import that module
into any other module that will use the API, and you only have to
write all of this once.

I personally prefer multiple modules, though it absolutely depends on
the demands of the project.

Re: [Tutor] Class errors
If the code I'm seeing is correct, the problem is the class is Jobs,
and you instantiated a Job, which doesn't exit.
Replace one with the other in either case should fix it.

Re: [Tutor] Python for linux
You're actually asking multiple subquestions here, let me start by asking a clarifying question: When you say "log in to the Linux machine" I assume you mean you need to access a remote host? Your script will be running locally? Next your other questions: Checking permissions of a file: Look into the os module. Checking for substrings: This is has many answers. Have you tried to do this yet?

Without the additional code to get the indexed item. index = (i for i, _ in enumerate(original_list) if original_list[i] >= target >= original_list[i + 1]).next() The only catch is it raises a StopIteration exception if no element fits the test.
