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
Simon

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

git production , development environment

I have a project of python files on a network drive called "Development".
I create branches off Development for new features and then merge back into Development once finished. Others in future will also do this.
I want to push "Development" into another separate folder called "Production" and for the life of me cannot figure out how to do this.
Please any suggests? How to do this?
Thanks.
I get this error when attempting.
Pushing to G:\03 GIS RESOURCES\05 GIS PROGRAMMING\Production
remote: error: refusing to update checked out branch: refs/heads/master
remote: error: By default, updating the current branch in a non-bare repository

remote: error:
remote: error: You can set 'receive.denyCurrentBranch' configuration variable to

remote: error: other way.

Option A
You can clone your Development project into another folder.
Synopsis:
git clone <repository> <directory>
Example:
git clone <path/to/Development> Production
Option B
Copy the content of folder Development (including .git folder) to folder Production.

Deploy pure python to heroku

I "finished" a little python project and I want to deploy it on heroku
GitHub page.
I want to execute: python2 main.py -i json-rpc
in order to have the json-rpc server listening for connections
but I get the following error when pushing to heroku:
$ git push heroku master Counting objects: 153, done. Delta
compression using up to 8 threads. Compressing objects: 100% (87/87),
done. Writing objects: 100% (153/153), 43.42 KiB, done. Total 153

-----> Heroku receiving push ! Heroku push rejected, no Cedar-supported app detected
To git#heroku.com:panager.git ! [remote rejected] master -> master
(pre-receive hook declined) error: failed to push some refs to
'git#heroku.com:panager.git'

What you might want to try doing is creating a Procfile. The full filename is Procfile, no extension, and it goes in the main directory of your project folder.
The content of that file would be:
web: python main.py -i json-rpc
Give that a shot and see if it works.
Alternatively, you may have forgotten to create a virtualenv for your app.
You should follow the instructions in Heroku's guide Getting Started with Python on Heroku
Update:
Having finally tested this myself on a fresh Heroku app, what you're missing is a requirements.txt. Even though you don't have any dependencies, you still need it. Within your virtualenv in the main project folder, run pip freeze > requirements.txt, and then git add . then git commit -m "added requirements.txt", and then push to Heroku and it should work.

Also, make sure that requirements.txt is saved with ANSI encoding, not Unicode or UTF-8! If you're a total n00b like me you can simply open requirements.txt in Notepad, choose SAVE AS and change the "Encoding" from the drop down. I tried all of the recommendations above but my error was due to this simple encoding problem.

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):
