-[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/GoogleCloudPlatform/python-docs-samples&page=editor&open_in_editor=appengine/flexible_python37_and_earlier/tasks/README.md
-
-Sample command-line programs for interacting with the Cloud Tasks API
-.
-
-App Engine queues push tasks to an App Engine HTTP target. This directory
-contains both the App Engine app to deploy, as well as the snippets to run
-locally to push tasks to it, which could also be called on App Engine.
-
-`create_app_engine_queue_task.py` is a simple command-line program to create
-tasks to be pushed to the App Engine app.
-
-`main.py` is the main App Engine app. This app serves as an endpoint to receive
-App Engine task attempts.
-
-`app.yaml` configures the App Engine app.
-
-
-## Prerequisites to run locally:
-
-Please refer to [Setting Up a Python Development Environment](https://cloud.google.com/python/setup).
-
-### Authentication
-
-To set up authentication, please refer to our
-[authentication getting started guide](https://cloud.google.com/docs/authentication/getting-started).
-
-### Install Dependencies
-
-To install the dependencies for this sample, use the following command:
-
-```sh
-pip install -r requirements.txt
-```
-
-This sample uses the common protos in the [googleapis](https://github.com/googleapis/googleapis)
-repository. For more info, see
-[Protocol Buffer Basics](https://developers.google.com/protocol-buffers/docs/pythontutorial).
-
-## Deploying the App Engine App
-
-Deploy the App Engine app with gcloud:
-
-* To deploy to the Standard environment:
-  ```sh
-  gcloud app deploy app.yaml
-  ```
-* To deploy to the Flexible environment:
-  ```sh
-  gcloud app deploy app.flexible.yaml
-  ```
-
-Verify the index page is serving:
-
-```sh
-gcloud app browse
-```
-
-The App Engine app serves as a target for the push requests. It has an
-endpoint `/example_task_handler` that reads the payload (i.e., the request body)
-of the HTTP POST request and logs it. The log output can be viewed with:
-
-```sh
-gcloud app logs read
-```
-
-## Creating a queue
-
-To create a queue using the Cloud SDK, use the following gcloud command:
-
-```sh
-gcloud tasks queues create my-appengine-queue
-```
-
-Note: A newly created queue will route to the default App Engine service and
-version unless configured to do otherwise.
-
-## Run the Sample Using the Command Line
-
-Set environment variables:
-
-First, your project ID:
-
-```sh
-export PROJECT_ID=my-project-id
-```
-
-Then the queue ID, as specified at queue creation time. Queue IDs already
-created can be listed with `gcloud tasks queues list`.
-
-```sh
-export QUEUE_ID=my-appengine-queue
-```
-
-And finally the location ID, which can be discovered with
-`gcloud tasks queues describe $QUEUE_ID`, with the location embedded in
-the "name" value (for instance, if the name is
-"projects/my-project/locations/us-central1/queues/my-appengine-queue", then the
-location is "us-central1").
-
-```sh
-export LOCATION_ID=us-central1
-```
-
-### Using App Engine Queues
-
-Running the sample will create a task, targeted at the `/example_task_handler`
-endpoint, with a payload specified:
-
-> **Note**
-> Please update
-> [create_app_engine_queue_task.py](./create_app_engine_queue_task.py) before running the following
-> command.
-
-```sh
-python create_app_engine_queue_task.py --project=$PROJECT_ID --queue=$QUEUE_ID --location=$LOCATION_ID --payload=hello
-```
