Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

Stores data elements based on an sequential, most commonly 0 based, index.

	"detect and conceal credit card info"
	import boto3
	client = boto3.client('comprehend', 'us-west-2')
	text = "1234 5678 9012 3456 05/24 CVV 123"
	print("detected text with credit card information", text)
	get_pii_indices = client.detect_pii_entities(Text=text, LanguageCode="en")
	replace_pii = None
	for i in get_pii_indices['Entities']:
	if i.get('Type') == 'CREDIT_DEBIT_NUMBER':
	credit_card_number_from_text = text[i.get('BeginOffset'): i.get('EndOffset')]

	# I like to refer to the following to remember how to use jinja2 :)
