Yeah, the overhead of the operating system adds a lot that you don't really need in a container.
Switching to an Alpine based image shaves off a lot i.e. just using FROM python:alpine instead of FROM python at the top of the file saves over 600MB:
FROM python:alpine
FROM python
$ docker image ls myapp.local REPOSITORY TAG IMAGE ID CREATED SIZE myapp.local latest b22d2c84a61c 3 seconds ago 98.1MB
