Awesome. Thank you all. Your solutions are great and should make the whole
process a lot more simple.
The only problem is that some_func() on my end is Django model with about 8
named arguments so it might be a bit of a pain passing all of those arguments.
The context manager example seems like a perfect fit for that particular
problem.
Thanks again. All of your help is much appreciated.

If you use PyTest, the procedure is pretty well documented:
