\$1 To use the Python 3.8 runtimes, you must create a symbolic link from the default Python 3.7 installation folder to the installed Python 3.8 binaries. For more information, see the connector-specific requirements.

**Note**  
We recommend that you [upgrade connector versions](connectors.md#upgrade-connector-versions) from Python 2.7 to Python 3.7. Continued support for Python 2.7 connectors depends on Amazon Lambda runtime support. For more information, see [Runtime support policy](https://docs.amazonaws.cn/lambda/latest/dg/runtime-support-policy.html) in the *Amazon Lambda Developer Guide*.
