I just started setting up a centos server today and noticed that the default version of python on centos is set to 2.6.6. I want to use python 2.7 instead. I googled around and found that 2.6.6 is used by system tools such as YUM so I should not tamper with it. Then I opened up a terminal on my mac and found that I had python 2.6.8 and 2.7.5 and 3.3.3 installed. Sorry for the long story. In short I just want to know how to lookup all the version of python installed on centos so I don't accidentally install it twice.

9 Answers. You can use python -V (et al.) to show you the version of Python that the python command resolves to. If that's all you need, you're done. But to see every version of python in your system takes a bit more.
The more easy way its by executing the next command:
ls -ls /usr/bin/python* Output look like this:
/usr/bin/python /usr/bin/python2.7 /usr/bin/pythonw /usr/bin/python-config /usr/bin/python2.7-config /usr/bin/pythonw2.7 we can directly use this to see all the pythons installed both by current user and the root by the following: whereis python
