Snakes & Gophers — A Python Dev's Guide to Thinking in Go

You've written Python for years. You can pip install your way out of anything. Your decorators are elegant, your list comprehensions are crisp, and you've finally gotten comfortable with asyncio . And then someone says — "we're moving to Go." This isn't a Go introduction. If you want that, head to Go by Example — it's the best.

You've fought with threading , embraced asyncio , maybe even used multiprocessing when things got desperate. Go throws all of that out. In Go, you have goroutines and channels . That's it. Goroutines are lightweight threads
