They may be valid responses, but we don't know if they are 
representative of the broader Python community. Its a self-selected 
survey of people which always makes the results statistically suspect.

(By definition, an Internet survey eliminates responses from people who 
don't fill out surveys on the Internet.)

BUt even if representative, this survey only tells us what version 
people are using, now how they invoke it. We can't conclude that the 
command "python" means Python 3 for these users. We simply don't know 
one way or another (and I personally wouldn't want to hazard a guess.)
