If you try to use serverless (the framework) for Python, you very quickly learn that its support is a second-class citizen vs building in TS/JS.

Adjacent concern but: It also makes for unholy large Docker images to combine an entire JS toolchain with an entire Python toolchain.

Zappa is a better (more native) choice.

Terraform modules provide a decent Python Lambda experience.

AWS also has multiple semi-overlapping projects in the space. Chalice, SAM, and Powertools specifically to name a few. CDK more generally as well.
