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:

Setting up a WordPress site on AWS

This tutorial walks through setting up AWS infrastructure for WordPress, starting at creating an AWS account. We'll manually provision a single EC2 instance (i.e an AWS virtual machine) to run WordPress using Nginx, PHP-FPM, and MySQL.

This tutorial assumes you're relatively comfortable on the command line and editing system configuration files. It is intended for folks who want a high-level of control and understanding of their infrastructure. It will take about half an hour if you don't Google away at some point.

If you experience any difficulties or have any feedback, leave a comment. 🐬

Coming soon: I'll write another tutorial on a high availability setup for WordPress on AWS, including load-balancing multiple application servers in an auto-scaling group and utilizing RDS.

	element = driver.find_element_by_id("coolestWidgetEvah")

	element = driver.find_element(by=By.ID, value="coolestWidgetEvah")

	# By class name:

	# List unique values in a DataFrame column
	# h/t @makmanalp for the updated syntax!
	df['Column Name'].unique()

	# Convert Series datatype to numeric (will error if column has non-numeric values)
	# h/t @makmanalp
	pd.to_numeric(df['Column Name'])

	# Convert Series datatype to numeric, changing non-numeric values to NaN
	# h/t @makmanalp for the updated syntax!
