Who on Earth would write "Python2" in their resume? I have "Python".
I mean this in the kindest possible way:
You're taking what I wrote too literally, and thus missing the point. What I wrote means: if the only Python you know is 2.x, it might close off opportunities for you in the near future.
18 months ago, the results were typically 20% Python 3, and 80% Python 2. Over time, the ratio shifted. In recent months, it's VERY consistently 60-70% Python 3; one class it was 80%.
As I tell those students: sooner than you think, having only Python 2 on your resume will make it look dated.
