I started learning Python 3.4 and would like to start using libraries as well as Google App Engine, but the majority of Python libraries only support Python 2.7 and the same with Google App Engine.

Should I learn 2.7 instead or is there an easier way? (Is it possible to have 2 Python versions on my machine at the same time?)

Google App Engine Python 3 Standard Environment documentation, Support for Python 3.x has been a requested feature on App Engine for years. Google App Engine brought Python 3.x to its flexible environment  Google App Engine Python 3 Standard Environment documentation Python 3 apps in the App Engine standard environment run within containers inside of secure sandboxes. Your apps scale automatically to meet traffic demand.

Since August 10, 2016, it does.

If you are using Google App Engine beta environment, you can edit your application app.yaml and specify the required Python version:

runtime: python
# vm: true has been deprecated
# check how env:flex may affect your billing
env: flex
entrypoint: gunicorn -b :$PORT main:app

runtime_config:
    python_version: 3

Quickstart for Python 3 in the App Engine Standard , In this codelab, you will learn how to deploy a simple Python web app written with the Flask web framework. Although this sample uses Flask, you can use other  Quickstart for Python 3 in the App Engine Standard Environment Region ID The REGION_ID is a code that Google assigns based on the region you select when you create your app. Including REGION_ID .r in App Engine URLs is optional for existing apps and will soon be required for all new apps.

Yes. Python 3.7 is available as a Google App Engine standard runtime as of August 8, 2018.

Understanding differences between the Python 2 and Python 3 , In this codelab, you'll learn to deploy a simple Python Flask web app to the App Engine It uses Google Cloud APIs for Cloud Vision, Cloud Storage, and Datastore. The App Engine flexible environment supports many programming languages, Create an isolated Python 3 environment named env with virtualenv: To deploy your web app to App Engine, you need an app.yaml file. This configuration file defines your web app's settings for App Engine. Create and edit the app.yaml file in the root directory of your project: touch app.yaml app.yaml runtime: python37. Note: With this simple web app, you just need to specify that you're using Python 3.7.

YES! Google App engine supports python v3, you need to set up flexible environments.

I got a chance to deploy my application on app engine and It's using python 3.6 runtime and works smoothly... :)

Migrating to the Python 3 standard runtime, Google App Engine is a Platform as a Service and cloud computing platform for developing and additional demand. Google App Engine primarily supports Go, PHP, Java, Python, Node.js, . This restriction does not exist with the App Engine Standard Java8 runtime. A process Retrieved 3 December 2019. ^ "​Python  Python 3 support is coming to Google App Engine's standard environment I just came across this little gem buried in a Google blog post with a vague title: "bringing the latest versions of Python 3 to the App Engine standard environment is on our roadmap."

Google App engine support python runtimes up to versions python v3.7 (till today).

Python v3.7 runtime fully supported by standard environment. (Non-flexible environment) and PiP packages in requirements.txt is also supported by standard runtime, will automatically install dependencies declared in requirements.txt.

app.yaml configuration for Python v3.7 follows below.

runtime: python37 
entrypoint: as you required. 

It's not required include runtime_config in app.yaml for python v3.7 standard environment.

Hooray: Google App Engine finally ready for Python 3 (and PHP 7.2 , Even though webapp2 3.0.0b1 (beta) does support Python 3, I would of life" in 2020, you will still be able to use it on Google App Engine. No bundled App Engine services in the Python 3 runtime. Starting with the Python 3 runtime, the App Engine standard environment no longer includes bundled App Engine services such as Memcache and Task Queues. Instead, Google Cloud provides standalone products that are equivalent to most of the bundled services in the Python 2 runtime.

Getting started with App Engine (Python 3) - Codelabs, Plus, App Engine automatically scales to support sudden traffic spikes without provisioning, patching, or monitoring. Below is a sample reference architecture for building a simple web app using App Engine and Google Cloud.

Deploy a web app to App Engine flexible environment, The App Engine environments App Engine is well suited to applications that are designed using a microservice architecture, especially if you decide to utilize both environments. Use the following sections to learn and understand which environment best meets your application's needs.

Google App Engine, The App Engine does not allow your application to spawn threads, but the app engine may launch multiple instances of your application or use some sort of threaded or multiprocess request handler. I don't know the specific details but without some sort of parallelism the app engine would be a pretty useless platform.
