Download python 2.7.2and follow the step. Just remember use make installdont do make altinstall, this will not make python 2.7as default python interpreter.
下载python 2.7.2并按照步骤操作。请记住使用make installdont do make altinstall，这不会python 2.7成为默认的 python 解释器。
Edit: Don't replace or uninstall python 2.6 if it came with distro, this might lead to breaking packages.
编辑：如果 python 2.6 随发行版一起提供，请不要替换或卸载它，这可能会导致软件包损坏。

You can also install python2.7 package. Then you can define python version with shebang (#!/usr/bin/env python2.7) or even use #update-alternatives --config pythonto make it default interpreter. But it can break a lot of system apps...
您也可以安装 python2.7 包。然后你可以使用 shebang ( #!/usr/bin/env python2.7)定义 python 版本，甚至可以使用#update-alternatives --config python它来使其成为默认解释器。但它可以破坏很多系统应用程序......
update: sometimes, there's no alternative to python, so you'll need to create those by hand. Something like update-alternatives --install /usr/bin/python python2.7 /usr/bin/python2.7 10
更新：有时，python 没有替代品，因此您需要手动创建它们。就像是update-alternatives --install /usr/bin/python python2.7 /usr/bin/python2.7 10
update2: nevertheless if you just need 2.7 for your project, I'd suggest using virtualenv: virtualenv -ppython2.7 myproject
update2：不过，如果您的项目只需要 2.7，我建议您使用 virtualenv： virtualenv -ppython2.7 myproject
