Not only because it just works - there might be projects also available on other platforms (other than Linux on x86) where P2 is still standard. So they cannot easily switch to P3 (and drop P2 support). But yes, having two Pythons on the machine is not that cool... -- Thomas -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.

I've heard there is one but that it cannot translate all code with perfect accuracy. I think many projects like to keep their Python 2 code because it works, changing it may only introduce "growing pains," and the perception is that the hassle outweighs the annoyance of installing two Python versions or the benefit of moving forward. -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.

Expecting to run a translator on the fly must be close to impossible, especially where the Python code is linked to C code, which is probably true for most packages. It might be possible to convert Python 2 to Python 3 manually on a package by package basis, but it would be a painstaking business.

And although I do recognize there may come a time to break backward compatibility, I still wish they'd provide a P2->P3 translator. -- Paul Rogers paulgrog...@fastmail.fm Rogers' Second Law: "Everything you do communicates."
