How to use Python3 Type Hints in AWS Lambda

TL;DR

Static Type Checkers help you find simple (but subtle) bugs in your Python code. Check out lambda_types.py and incrementally improve your code base and development/debugging experience with type hints.

Your Lambda Function code will go from this:

jpetazzo

# this forces dpkg not to call sync() after package extraction and speeds up install
RUN echo "force-unsafe-io" > /etc/dpkg/dpkg.cfg.d/02apt-speedup
# we don't need and apt cache in a container
RUN echo "Acquire::http {No-Cache=True;};" > /etc/apt/apt.conf.d/no-cache
