Sign-in to Google Cloud Platform console (console.cloud.google.com) and create a new project (or reuse an existing one): Remember the project ID, a unique name across all Google Cloud projects (the name above has already been taken and will not work for you, sorry!). The end of each written section includes a link to the code exercise for that section's material. After invoking each function, the test checks the HTTP response to be sure it was what we were expecting. Let's make the "Hello World!" If it is not, you can set it with this command: After Cloud Shell launches, you can use the command line to invoke the Cloud SDK gcloud command or other tools available on the virtual machine instance. Check the error message for anything helpful. To test the hello_name function, copy the httpsTrigger URL that's displayed in the gcloud functions deploy output. This will make sure we can deploy Cloud Functions later in the codelab. To specify the dependencies of your web app, create a requirements.txt file in the root directory of your project with the exact version of Flask to use: Note: The only dependency in your web app is Flask. Google Cloud Functions is an event-driven serverless compute platform. If it is not, you can set it with this command: Run the following command from Cloud Shell to make sure the Cloud Functions API is enabled. Let's deploy this function as an HTTP Cloud Function! Deploy this function as you did the "Hello World!" To get started, the Python sections are linked at the left -- Python Set Up to get Python installed on your machine, Python Introduction for an introduction to the language, and then Python Strings starts the coding material, leading to the first exercise. Next, you'll need to enable billing in the Cloud Console in order to use Google Cloud resources. First, set the PROJECT_ID environment variable: Test your web app with this simple HTTP GET request: Note: Your web app can be served via a custom domain, such as example.com, instead of the default appspot.com address. Sign up for the Google Developers newsletter. The lecture videos parallel the written materials, introducing Python, then strings, then first exercises, and so on. Special thanks for the help from my Google colleagues John Cox, Steve Glassman, Piotr Kaminksi, and Antoine Picard. The new version of your app gets deployed: Note: The new version is transparently deployed and traffic is automatically routed to it (if successfully deployed). Did you get an error during deployment? You'll build one in this codelab. Google Developers Codelabs provide a guided, tutorial, hands-on coding experience. To set it, we'll add a URL parameter name=YOURNAME to the URL. If everything is working correctly, you will see the ‘Python Powered' logo in your browser! Congratulations! Intelligent Python 3.6.9 IDE with syntax recognition and auto text formatting and more awesome feature from iLabs corporation. Once connected to Cloud Shell, you should see that you are already authenticated and that the project is already set to your PROJECT_ID. Cloud Functions allows you to write your code without worrying about provisioning resources or scaling to handle changing requirements. Python is a popular open source programming language used by data scientists, web application developers, systems administrators and more. To deploy your web app to App Engine, you need an app.yaml file. You'll see that we're getting the default result because we haven't set the name argument. Although this sample uses Flask, you can use other web frameworks, including Django, Pyramid, Bottle, and web.py. It will be referred to later in this codelab as PROJECT_ID. This tutorial is adapted from https://cloud.google.com/appengine/docs/standard/python3/quickstart. Click the Web Preview button , select "Change Port" and then enter port number 5000 in the displayed input. If there was no error when writing the response, the function returns normally. You can open this file in Cloud Shell by opening the editor (click the pencil icon at the top right of Cloud Shell) then using the file tree on the left side of the editor to open the file, python-docs-samples-master/codelabs/functions/python_powered/main.py. For more information and a list of all the supported elements, see the app.yaml reference. There is no need to run an emulator or other simulation to test your function—just normal Python code.
