Python

I started writing in the 2010s when Python 2 was going to be deprecated and Python 3 was too early to support. Python might have died there and then but was picked up by the data science and machine learning community, so, it survived. Running Python in production comes with various gotchas though. Python is resource-intensive Let’s consider a simple Docker image containing “Hello World”. Dockerfile 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 # Build: docker buildx build -t python-fastapi -f Dockerfile_python . # Size: docker image inspect python-fastapi --format='{{.Size}}' | numfmt --to=iec-i # Run: docker run -it --rm --cpus=1 --memory=100m -p 8000:8000 python-fastapi FROM python:3.12-slim AS base WORKDIR /app RUN pip3 install --no-cache-dir fastapi==0.115.11 uvicorn==0.34.0 SHELL ["/bin/bash", "-c"] RUN echo -e "\ from fastapi import FastAPI\n\ app = FastAPI()\n\ @app.get('/')\n\ async def root():\n\ return {'message': 'Hello World'}\ " > /app/web_server.py ENTRYPOINT ["uvicorn", "web_server:app", "--host=0.0.0.0", "--port=8000", \ "--workers=4", "--limit-concurrency=32"] And a similar web server in Go. ...

As the title suggests, I was looking for a way to send HTML mails in python using Amazon SES but did not find anything (or maybe my search skills are bad). So, once I found the solution, I thought I might share it with everyone. The basic idea is that contents of the mail (raw-message) must be a JSON dictionary with “Data” as main key whose value is a key value pair containing entries with keys like “From”, “To” etc. Sample code can be seen below.
