Centos 6.5 does not cover py2.x installation of python3.3.2

I recently went to the plateau and didn't want to read books. I simply wanted to learn PHP, but accidentally came into contact with python. How did you say I wouldn't learn? Right?

How to install python3.3.2.

Before that, it should be clear: centos6.5 itself is installed with python, 2.6.6 and 2.4, which is used for which link is used; others, for example, UBUNTU also comes with python, but the version is relatively low.

At this time, if you enter python in the interrupt, version 2.6 will be released, because the path has not been modified, that is, although you installed 3.3.2 during the connection, but there is no link, so you do not need 3.3.2, so you need to link:
What happened? As you can see, the folder conflicts during the link, and the original folder name is not modified, so we should first look like this:
The red part is the modified file name, which can be changed at will, but you must remember it
