11 I use 'eselect python list' to see what options you have.
12
13 Then I'd go to bugs.gentoo.org and poke around for any bug reports
14 on python-3.4.*

25 Use a -p to see what it proposes to do first....

30 I would not unmerge any version just yet. If a package absolutely needs
31 python-3.4, it will let you know when you use a -p option.
32
33 I'd also keep python 2.7 around a while longer, just to be safe.
34 Keeping several old stable versions of python around is a good
35 idea, imho.

40 Best thing is to look for bug reports on 3.4.* with python.
41 It is stable so there should not be anything significant.
42
43 Note: without a working version of python, you system may become
44 hosed, so be cautious with python as it is system critical.
