Not the poster you're asking, but in my case, have used Python extensively for cloud-related programming, lots of AWS lambda. Currently in a special kind of hell trying to move our company's lambdas from Python 2 to Python 3. It should be easy but there's an internal Python 2 library that is in everything that is massive and almost impossible to excise without significant effort. Started writing lambdas in Go, you ship your compiled binary and the lambda environment will never care what version you're running. Shipping a binary means I'm no longer worried about my build environment and pip and shipping all my Python junk the right way. Also in other areas, simply transposing some code to Go has had huge performance benefits over Python and concurrency is just so easy to pull off.
