I just installed Ubuntu 12.04 and wish to use Python 3.3 rather than 2.7 which is currently installed. I downloaded python from python's ftp and installed it. I followed the steps given in : https://askubuntu.com/questions/244544/how-to-install-python-3-3

现在，我在/opt/python3.3中安装了Python 3.3，并按照此URL中的说明为其创建了符号链接.仍然python --version命令告诉我我的当前版本是2.7.3.

Now I have Python 3.3 installed in /opt/python3.3 and create sym links for it as told in this URL. Still python --version command tells me that my current version is 2.7.3.

怎么了?
