Answer 1

Your Problem

remote:Requested runtime (python-3.5.2) is not available for this stack (heroku-18)

Solution:

by the official website of heroku , your python version (3.5.2) isn't compatible with heroku version 18.

From Developer Webpage:

Specifying a Python version

By default, newly created Python apps use the python-3.6.8 runtime. You can also specify a different supported Python version.

Supported runtimes

• python-3.7.3 on all (heroku-16, and heroku-18) runtime stacks
• python-3.6.8 on all (heroku-16, and heroku-18) runtime stacks
• python-2.7.16 on all (heroku-16, and heroku-18) runtime stacks
