I bet they know how versions work though, and that 3.7 is higher than 2.7. I just googled ‘Python tutorial’ and only one of the results on the first page was for python 2. The first result was ‘The Python Tutorial — Python 3.7.3 documentation’. If some non-programmer was going to start learning python, they’re most likely going to start with google. I can’t see them digging deeper into the results because they want to learn an older version of the language.
