The problem you are having has nothing to do with the python version. What heroku is saying is that you should change to python 3.6.6 which you do by adding a file to the project - see https://devcenter.heroku.com/articles/deploying-python.
The problem you are getting (and that hinders you from installing your application) is that you are using a python 2.7 compatible plugin (Cheetah) - that doesn't have any python 3 code. The error is that the code is not python 3 compatible. (the syntax error you are getting at the end shows this) - to install a Cheetah that you can use, install cheetah3.
