This environment is identified\nby the language version, and is known as the runtime ID.\n\nFunction preparation\n--------------------\n\nYou can prepare a function directly from the Google Cloud console or write it on\nyour local machine and upload it. To prepare your local machine for Python\ndevelopment, see [Set up a Python development environment](/python/docs/setup).\n\nSupported Python runtimes and base images\n-----------------------------------------\n\nSelect your runtime\n-------------------\n\nYou can select one of the supported Python runtimes for your function during\ndeployment.\n\n\nYou can select a runtime version using the Google Cloud console, or the\ngcloud CLI. Click the tab for instructions on using the tool of\nyour choice: \n\n### gcloud\n\nSpecify the [Python base image](/run/docs/configuring/services/runtime-base-images#how_to_obtain_base_images) for your function using the `--base-image` flag,\nwhile deploying your function. For example: \n\n gcloud run deploy \u003cvar translate=\"no\"\u003eFUNCTION\u003c/var\u003e \\\n --source . \\\n --function \u003cvar translate=\"no\"\u003eFUNCTION_ENTRYPOINT\u003c/var\u003e \\\n --base-image python313\n\nReplace:\n\n- \u003cvar translate=\"no\"\u003eFUNCTION\u003c/var\u003e with the name of the function you are\n deploying. You can omit this parameter entirely,\n but you will be prompted for the name if you omit it.\n\n- \u003cvar translate=\"no\"\u003eFUNCTION_ENTRYPOINT\u003c/var\u003e with the entry point to your function in\n your source code. This is the code Cloud Run executes when your\n function runs. The value of this flag must be a function name or\n fully-qualified class name that exists in your source code.\n\nFor detailed instructions on deploying a function using the gcloud CLI, see [Deploy functions in Cloud Run](/run/docs/deploy-functions#gcloud).\n\n### Console\n\nYou can select a runtime version when you create or update a Cloud Run function in the Google Cloud console. For detailed\ninstructions on deploying a function, see [Deploy functions in Cloud Run](/run/docs/deploy-functions#deploy-functions).\n\nTo select a runtime in the Google Cloud console when you create a function, follow these steps:\n\n1. In the Google Cloud console, go to the Cloud Run page:\n\n [Go to Cloud Run](https://console.cloud.google.com/run)\n2. Click **Write a function**.\n\n3. In the **Runtime** list, select a Python runtime version.\n\n4. Click **Create**, and wait for Cloud Run to create the service\n using a placeholder revision.\n\n5. The console will redirect you to the **Source**\n tab where you can see the source code of your function. Click **Save and redeploy**.\n\nFor detailed instructions on updating the runtime version after your function is\ndeployed, see\n[Re-deploy new source code](/run/docs/deploy-functions#update-code-functions).\n\nSource code structure\n---------------------\n\nFor Cloud Run functions to find your function's definition, your\nsource code must follow a specific structure. See\n[Write Cloud Run functions](/run/docs/write-functions#python) for\nmore information.\n\nSpecifying dependencies\n-----------------------\n\nThere are two ways to specify dependencies for Cloud Run functions\nwritten in Python: using the `pip` package manager's `requirements.txt` file or\npackaging local dependencies alongside your function. For more information, see\n[Specify dependencies in Python](/run/docs/runtimes/python-dependencies).\n\nCloud Run functions doesn't support specifying dependencies with\nthe `Pipfile/Pipfile.lock`, so your project shouldn't include these files.\n\nEnvironment variables\n---------------------\n\nYour Python runtime automatically sets certain environment variables for your\nfunction to use as needed. For details, see [Configure environment\nvariables](/run/docs/configuring/services/environment-variables)."]]
