Explained below, underneath each pertinent info you provided. First, let's discuss Python 2.6: On 01/06/2013, Νικόλαος Κούρας <nikos.gr...@gmail.com> wrote: > I'am using CentOS v6.4 on my VPS and hence 'yum' install manager and i just > tried: > > Code: > root@nikos [~]# which python > /usr/bin/python This is the version of that CentOS 6 is using. It is Python 2.6 as shown in the next paragraph. This version is essential to CentOS 6. This cannot be changed or upgraded without so much work that no sane person on the planet would bother. Stop worrying about it. On 01/06/2013, Νικόλαος Κούρας <nikos.gr...@gmail.com> wrote: > > root@nikos [~]# python -V > Python 2.6.6 See above.

Stop worrying about it. Now let's talk about yum: On 01/06/2013, Νικόλαος Κούρας <nikos.gr...@gmail.com> wrote: > root@nikos [~]# yum remove python3 [...] > No Match for argument: python3 [...] > root@nikos [~]# yum remove python3.3 [...] > No Match for argument: python3.3 > > i don'y understand, why didnt it removed it neither of ways? Your yum setup does not find python3 or python3.3 packages. So you could not have used yum to install it. Therefore, you cannot use yum to remove it. And, you cannot use yum to install it. Now let's talk about Python 2.7: On 01/06/2013, Νικόλαος Κούρας <nikos.gr...@gmail.com> wrote: > root@nikos [~]# which python3 > /root/.local/lib/python2.7/bin/python3 There's a python2.7 directory there under /root/.local. Maybe you installed python2.7 from source using some kind of 'make install' command (ie not using yum)? If so, and you wish to remove it, there will probably be another 'make' command to remove it, which must be run from the same directory that you ran 'make install'. Try 'make help' in that directory. Maybe someone else can explain why there is a python3 command under that directory, because I can't. Now let's talk about Python 3: On 01/06/2013, Νικόλαος Κούρας <nikos.gr...@gmail.com> wrote: > > root@nikos [~]# ls -al /usr/bin/python* [...] > lrwxrwxrwx 1 root root 24 Apr 7 22:10 /usr/bin/python3 -> > /opt/python3/bin/python3* There's a python3 directory there under /opt. Maybe you installed python3 from source using some kind of 'make install' command (ie not using yum)? If so, and you wish to remove it, there will probably be another 'make' command to remove it, which must be run from the same directory that you ran 'make install'. Try 'make help' in that directory.

When trying something you don't fully understand, first experiment somewhere you don't care if bad things happen.

Don't install or remove them until you understand the different things they do. -- http://mail.python.org/mailman/listinfo/python-list
