why would I look at Python for performance when Go exists? If you're aware of the issues and have other options, you wouldn't look to Python for performance unless it was a case where Python is just used to script pre-existing C libraries (ex: machine learning). For general performance, you would choose Go over Python. If you choose Python, it will be for some other reason such as ease of programming, extensive and well-developed libraries, ease of hiring Python programmers, etc., where Python is better than Go and fast enough. I've always loved Python and have done a LOT of it (professionally and privately) over many years, but Go has replaced most of it. Having fast, concurrent apps statically compiled into a single executable is a huge improvement for many of my uses of Python, esp. server-side apps and local command line utilities. But I would still prefer Python as a teaching language, for machine learning, for quick one-off tasks (ex: format an ugly chunk of copied data into C++ source code), and possibly for code that I wanted others to write and maintain for me. (Python programmers are easier to hire than Go programmers.)
