I've recently installed Ubuntu 19.04 which has Python 3.7 by default. I need to work on multiple projects that use Python 3.6.

Is there a way to install it on Disco Dingo?

I tried which works on 16.04

I'm trying to get my cookiecutter-django app running under Apache with mod_wsgi installed via pip.

python3 manager.py runserver works.

But after running it in Apache, I got an error saying Module config not found. So I pip install config. (It is not installed on my development system.)

That put a config.py file in my /usr/local/pulseenv/lib/python3.5/site-packages.

That file had various syntax errors which I fixed. The errors were due to changes between python 2.7 and 3.5 as far as I can tell.

But now I get this error and I'm stuck where to go from here:

My friend just started learning Python and Flask, and is missing a lot of "best practices", e.g., a requirements.txt file.

He has recently asked me for assistance, and to make the project clean, I want to setup a CI service (Travis), but I need to work out this file first.

Since he did not initially have a requirements.txt, all information I can have is his import statements, as well as his output of pip freeze.

As there's no way to distinguish a direct requirement by the project and an indirect requirement by one of the packages, I want to find out all "top-level" packages from the list. A "top-level package" is a package that's not required by another package in the list. For example, urllib3 is required by requests, so when requests is present, urllib3 may better not appear in the final result.

Is there a way to achieve this?

If anyone wants to help me with this specific instance, here's the output of pip freeze:
