I started a project at work on Python 1.5, and it was a bit disruptive when I had to move it to 2.0, and even 2.1 was some disruption from that. I continued supporting that project for between 10 and 15 years and kept it at Python 2.x even after Python 3 was out.
At the time I figured I would be retired before I needed to move to Python 3, but I was wrong. I ended up moving to 3.x several years before retiring this past spring. Part of the problem is that RedHat Enterprise last I knew shipped Python 2.7 by default. The company also had local installations of Python 3.x, and both versions had semi-overlapping additional libraries, which was quite annoying. I actually had some code that was split between the two versions and passed intermediate data between them.
