Getting started with Python Development

Setting up your Dev Environment

Highly recommend using VSCode for developing.
Learn and always use virtual environments: venv
Highly recommend only developing on a Mac or Linux. If you are on Windows you can use Docker + VSCode to give you a Linux shell. This will reduce your likely hood of having problems install dependencies.
I really love using ptpython and ptipython because it helps with autocomplete. https://github.com/prompt-toolkit/ptpython
Real Python is definitely one of the best resources from learning Python. This is their Intro Learning Path https://realpython.com/learning-paths/python3-introduction/

pg_dump -p 5432 database_name > database_name_data.sql

psql -U username -d database_name -f objects.sql

pg_restore --verbose --clean --no-acl --no-owner -h localhost -d [db_name] db_backup.dump

Open React Native Debugger first and set the RN publishing Port to 19001. Then enabled Debug Remote JS in the Expo app.

React Native Debugger

I'm able to visually identify and understand React components. However, I do not know the names used to identify them.

class MyList extends React.Component {...}

function App() {return (...)}

kill $(ps -e | grep hung_tasks | awk '{print $1}')

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

	#!/bin/bash

	# Set default region (you can modify this)
	AWS_REGION="us-east-1"

	# Error handling function
	error_exit() {
	echo "Error: $1" >&2
	exit 1
	}

	export $(printf "AWS_ACCESS_KEY_ID=%s AWS_SECRET_ACCESS_KEY=%s AWS_SESSION_TOKEN=%s" \
	$(aws sts assume-role \
	--role-arn arn:aws:iam::123456789012:role/MyAssumedRole \
	--role-session-name MySessionName \
	--query "Credentials.[AccessKeyId,SecretAccessKey,SessionToken]" \
	--output text))

	# Python dict.iteritems became just dict.items.
	# Easily coherse the generator into a list with: `list(gen_dict_extract("KeytoFind", MyDict))`

	def gen_dict_extract(key, var):
	if hasattr(var, 'items'):
	for k, v in var.items():
	if k == key:
	yield v
	if isinstance(v, dict):
