Build on Heroku , Git issue with Push Failed, error in message :)

me again...can I please have some help, going a little bonkers here..
I have a simple Python script that I would like to connect to a scheduler task in Heroku...Its all going fine until I try deploy to Heroku. Its super simple script and its doing my mind in trying to work out why I cant deploy it.
Followed the instructions exactly from here..

Ive been into Heroku web interface and selected buildpack of Python (hoping that might be it), but still no luck.
Im on a Mac, using Visual Studio Code, with embedded terminal.
Any thoughts people?
Would be so grateful for any help.
Thanks again

problem pushing changes to GitHub because of file that's not really there

I imported TensorFlow to the project but then removed it, when trying to delete it from the terminal it's not there (and when looking for it manually).
any help would be appreactied!

Since you should not push any generated binary file anyway, start first by removing them locally, commit and push:
git rm -r '*.so' -f
echo '*.so' >> .gitignore
But if that still fails, it means you are trying to push past commits (not just the latest one) with *.so files, even though the last commit no longer includes any such files.
If that is the case, since git filter-branch is soon deprecated, consider newren/git-filter-repo to remove any large files like those *.so ones, before pushing (or force pushing of that rewrites the content of past commits previously pushed).

There is a problem with the code, I can not find a solution

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

GitPython debug logs not available

In case I run a simple git command like
git fetch origin

From https://github.com/edorado93/jocular
* branch master -> FETCH_HEAD
ed17d20..6e70ecd master -> origin/master
I want similar logs while executing this command using GitPython module. So the command goes something like this
git.fetch('origin')
I set the environment variable type(repo.git).GIT_PYTHON_TRACE="full" . Still on executing my script, I don't get any git logs on the console.
What am I missing here ?

You're missing the logging, without which GitPython doesn't seem to want to log anything:
import logging
logging.basicConfig(level=logging.INFO)
An example after this:
from git.cmd import Git
g = Git()
type(g).GIT_PYTHON_TRACE="full"
g.fetch('origin')
which outputs:
INFO:git.cmd:git fetch origin -> 0
''

How to download the Enthought Tool Suite python script?

I have Python downloaded already, but want to contribute code to the Enthought Tool Suite (ETS). According to this site (http://code.enthought.com/source/):
it says to download the following python script: https://raw.github.com/enthought/ets/master/ets.py
I put the ets.py into the python script, save as...and in the Python Shell, I typed in "import ets"
However, nothing happens.
Also, the site says to run the following commands:
$ mkdir ets
$ cd ets # and copy ets.py here
$ python ets.py clone
Typing those lines in Python Shell gives me the message: "SyntaxError: invalid syntax"
As you can see, I'm new to Python, and I don't know what I'm doing. How do I download the ETS script and run the commands??

Those last commands aren't meant to be entered into the Python console, they're meant to be entered at the terminal shell.
localhost-2:tmp $ mkdir ets
localhost-2:tmp $ cd ets
localhost-2:ets $ cp ../ets.py .
This last command assumes that ets.py was in the original directory. Now we can run it [edit: make sure you have git installed, or this won't work]:
localhost-2:ets $ python ets.py clone

After this, you need to install everything (this will look different depending on your operating system):
