pypi deploy failing for python 2 with "SyntaxError: invalid syntax"

[bcavagnolo]

Hello. My python deploy started failing recently. Here's an example: https://travis-ci.org/github/planetlabs/datalake/jobs/758113984

Poking around the dpl source, I suspect that the issue is that the mainline get-pip.py script recently dropped support for python 2. A solution is articulated here on stack overflow:

https://stackoverflow.com/questions/65866417/pip-install-failing-on-python2/65866547#65866547

Does dpl/travis intend to continue supporting shipping python 2 packages to pypi?

After some experimentation I introduced a pretty deplorable work-around for this to unblock my immediate needs: planetlabs/datalake@e755c91

The issue is here in the dpl source code: https://github.com/travis-ci/dpl/blob/master/lib/dpl/assets/pypi/install#L3

I created this pull request in an attempt to fix the problem: #1233

....but I suspect that I'm still missing something. Like, is there a travis image on which this script works? Or is there some configuration that points dpl to use a specific version of python?
