As Selcuk and warmoverflow said, both versions of python , python 2.x and 3.x comes already installed on ubuntu. 正如Selcuk和warmoverflow所说，ubuntu上已经安装了python，python 2.x和3.x两个版本。 However if you want to upgrade your python version, say python 2.7.6 to python 2.7.11 or so, you can upgrade it by downloading the latest version and building it from source. 但是，如果要升级python版本，例如将python 2.7.6升级到python 2.7.11，则可以通过下载最新版本并从源代码构建它来进行升级。
