I'm using Centos,python for 2.7.3.

about how to change the version of Python to 2.7.3, you can see this article, the following is the installation of Python from this connection to the

http://www.zhangchun.org/the-centos6-3-upgrade-python-to-2-7-3-version/

1. Download Python-2.7.3

Wget http://python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2,

2. Unzip the Python-2.7.3

TAR-JXVF python-2.7.3.tar.bz2

3. Go to the folder you just unzipped

CD Python-2.7.3

4. Installation

$./configure$ make all    $ sudo make install$ make clean$ make Distclean

5. View version Information

/usr/local/bin/python2.7-v

6. Establish a soft connection so that the system default Python points to python2.7
Under normal circumstances, even if the python2.7 installation succeeds, the system pointing to Python is still the 2.6.6 version, considering that Yum is based on python2.6.6 to work properly and does not dare to uninstall easily.

How do you point to the system default Python to version 2.7?

Mv/usr/bin/python/usr/bin/python2.6.6ln-s/usr/local/bin/python2.7/usr/bin/python

7. Fix system Python soft links to python2.7 version, Yum does not work properly

Vi/usr/bin/yum

The file header is
#!/usr/bin/python
Change into
#!/usr/bin/python2.6.6

The entire upgrade process is complete and you can use the Python2.7.3 version.
