Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

	cigar
	rebut
	sissy
	humph
	awake
	blush
	focal
	evade
	naval
	serve

	#!/bin/bash

	digits='[[:digit:]].*[[:digit:]]'
	upper='[[:upper:]].*[[:upper:]]'
	lower='[[:lower:]].*[[:lower:]]'
	punct='[[:punct:]].*[[:punct:]]'

	stringPasswordCounter=0
	weakPasswordCounter=0

	import random
	randList = [random.randrange(1,100) for _ in range(10)]
	print(randList)

	i=0
	j=len(randList)-1

	while i<j:
	if randList[i]%2==1:
	swap=False
