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:

from statsmodels.robust.scale import huber

mean, std_dev = 0, 2
sample_size = 25
np.random.seed(42)
x = np.random.normal(mean, std_dev, sample_size)

# Appends a couple of outliers
