ERROR:Deploying Python app using heroku CLI

When I enter
$ git push heroku master
It Shows:

Updating specific files with git for django app on heroku

I deployed my django app to heroku and its working well. When I change something in project on local files and want to push to heroku It always push all files and it takes time.

The file that I changed around 1mb but it pushes 280mb. So what's the problem with it?

If you don't want to push your static file for every time then run this command :
heroku config:set DISABLE_COLLECTSTATIC=1
Enable static file for future:
heroku config:unset DISABLE_COLLECTSTATIC(for future use).

Push rejected, failed to compile Python app - Python version error

I have used Heroku with PHP in the past but this is the first time I am using Heroku with Python and Flask. For start, I want to create a simple "Hello World" app and then upload a more complex program I have built. Therefore the project's folder contains the following:
One "Hello World" Python script (called Main.py):
from flask import Flask, render_template
app = Flask(__name__)
#app.route("/")
def index():
return render_template("index.html", message="Hello World")
if __name__ == "__main__":
app.run(debug=True)
A templates file with a index.html file (see above) inside it
One runtime.txt file:
python-3.6.5
One requirements.txt file:
Flask==1.0.1
(The project is originally located at /Users/User/PycharmProjects/Project_HelloWorld.)
However, when I enter git push heroku master at the terminal then I am getting the following error:

How can I fix this error and properly run my app on Heroku?
Also when I am entering cat runtime.txt at the terminal for the runtime.txt above then I am getting the following (quite unexpected?) output:

python-3.6.5}%
I have firstly tried it with python-3.6.4 (instead of python-3.6.5) in the runtime.txt but I was getting the same error.

First I'd figure out how to run your app with gunicorn, as that's the most common deployment server for Flask apps. To run your app with gunicorn, you should be able to pip install gunicorn, then run from the root of your project: gunicorn my_file_name:app, where my_file_name == the name of the file that contains your Flask code above. E.g. if your Flask code is in a file named app.py, you'd run gunicorn app:app.
Once you can run the app with gunicorn, create a Procfile that specifies you want Heroku to run the server with gunicorn. Here's the contents of Procfile, which should be in the root of your project files (the same directory with requirements.txt):
web: gunicorn app:app
Then I'd update requirements.txt. Do a pip freeze | grep gunicorn to get your gunicorn version then add it to the requirements.txt file:
Flask==1.0.1
gunicorn==19.7.1
Finally, to resolve the immediate cause of your error above, I'd set runtime.txt to:
python-3.6.4
Then git push heroku master should be able to get you going...
If all else fails, here's a simple repository that has a barebones Flask app with Heroku deployment instructions in the README. It's deployed here: https://myapp-name-1.herokuapp.com/

So I found what it was going wrong and now my "Hello World" can run properly on Heroku.
The problem was the that even though I created anew the runtime.txt file and the requirements.txt for some reason the following "text" was inserted in them before the proper text:
\rtf1\ansi\ansicpg1252\cocoartf1561\cocoasubrtf200
remote: {\fonttbl\f0\fmodern\fcharset0 Courier;}
remote: {\colortbl;\red255\green255\blue255;\red43\green47\blue49;\red237\green237\blue244;}
remote: {\*\expandedcolortbl;;\cssrgb\c21961\c24314\c25098;\cssrgb\c94510\c94510\c96471;}
remote: \paperw11900\paperh16840\margl1440\margr1440\vieww10800\viewh8400\viewkind0
remote: \deftab720
remote: \pard\pardeftab720\partightenfactor0
remote:
remote: \f0\fs26 \cf2 \cb3 \expnd0\expndtw0\kerning0
This was displayed at the error that I posted above when I was trying to do git push heroku master at my app and when I was entering cat runtime.txt. I finally spotted this by using a Hex editor. Therefore, Heroku was not only reading python-3.6.4 in my runtime.txt but also all this thing that I posted above before actually reading python-3.6.4. and this is the reason why I was getting an error.
As #Chris notes below at the comments, this unnecessary "text' was added (for some reason) because my .txt files were firstly saved (for some reason) as .txt.rtf and then I manually changed the extension to .txt without having in mind that something more was saved in them even thought I changed the extension. I deleted all this unnecessary "text" with my Hex editor and now everything is working fine.

Django error deploying to heroku requirements

I am trying to deploy my a django app to heroku. I have a virtual environment(of course). I have the procfile, setup.py and runtime.txt set up correctly. It runs perfectly on a local development server, but when I push to heroku it gives some kind of error with the requirements file.
This is the third traceback after pushing to heroku. I changed the procfile the first two times and then it only gave errors with the procfile. Now that the procfile errors are gone I have some kind of error with this.
Traceback:

runtime.txt:

I can install the dependancies locally from the requirements.txt file and the other thing is when I try to update pip it says it is already up to date. My runtime environment is set to python 3.5.1. The app crashes when it is deployed and I am assuming it is because of the traceback errors. What can I do to fix this?

How was the requirements.txt file created? Is it possible it is corrupted or not plain text or has non-printable characters in it?
I recommend deleting requirements.txt and generating it cleanly based on pip freeze.
If you are using Windows Powershell the encoding issue could be affecting you. The suggested solution is:
pip freeze | Out-File -Encoding ASCII requirements.txt

How can I tail logs from OpenShift to be verbose about python setup.py, virtualenv, and pip?

When I run:
rhc tail -a myapp
I do see a stream of log messages at app startup, but nothing about the setup of the virtualenv and installation of dependencies in requirements.txt, like flask etc. How can I better monitor this on the server for the purposes of debugging, in case I run into a problem? This is fairly easy to do in Heroku, but I'm considering migrating apps to OpenShift, but only if options for debugging python are very flexible.

When you git push changes to your app you OpenShift responds with detailed output regarding the status of setup.py, requirements.txt, etc. Here is sample (abbreviated) output from a deployment to a Python app on OpenShift:

Best thing to do imo in this case is to ssh into your gear. Once logged in you can change into the app directory and view all log/config files directly.
