Setting Your Python Version
Issues deploying your Python app? See Troubleshooting Python Deploys.
Python version 3.11.9 is the default for Render services created on or after 2024-04-04.
Specify a different Python version by setting your service’s PYTHON_VERSION environment variable to a valid Python version (e.g., 3.11.7). You can specify any released version from 3.7.0 onward.
Render doesn’t support unreleased Python versions natively, but you can use them via Render’s Docker support.
History of default Python versions
If you don’t set a Python version for your service, Render’s default version depends on when you originally created the service:
| Service Creation Date | Default Python Version |
|---|---|
2024-04-04 and later | 3.11.9 |
2024-02-22 to 2024-04-04 | 3.11.8 |
2024-01-02 to 2024-02-22 | 3.11.7 |
2023-12-04 to 2024-01-02 | 3.11.6 |
Before 2023-11-01 | 3.7.10 |
