My advice to new programmers is completely opposite this. I recommend that people learn Python 3 and use it until they have a specific reason not to. Most new programmers can work with Python 3 and never run into difficulty.

If someone needs to use 2.7 for a specific project, it's easy to adapt if you're well grounded in Python 3. There's no reason these days to tell beginners to start with Python 2.
