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. I'm also not going to list conceptual differences between Python and Go — you're one search away from that. This guide is about rewiring your instincts. Python and Go look different on the surface, but they think differently underneath. And that's where the real adjustment happens. The Big One: Concurrency This is the only section that needs real focus. Everything else is honestly just language flavour. Python has the GIL and the event loop. 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 mana
