My interpretation of the usage share is that Golang ate a bunch of lunch that would've otherwise gone to Python. That is, people moving from other languages (Perl, PhP) to something else for various reasons. Absent Go, I suspect many current Gophers would've landed on Python. So in a sense, Python lost people to Go. But I've never seen anything to indicate that there was a large migration from Python to Go, and certainly not because of 2 to 3 or public perception--whatever that means in the context of a programming language. Python 2 is still the mainstay for Data Scientists. I've seen more resistance to moving to 3 there than almost anywhere. Which is pretty funny because it's the easiest code to port assuming your data science libs support 3 (and all the big ones do.) I think it's more accurate to say that Go ended up with some of Python's potential mindshare, not that it stole a significant amount of existing mindshare.
