Python is an object-oriented, literal translation of computer programming language, but also a http://www.aliyun.com/zixun/aggregation/17547.html "> powerful and perfect universal language, has a more than 10-year history of development, Mature and stable. This language has a very simple and clear grammatical features that are suitable for performing various high-level tasks and can be run in almost all operating systems. At present, the relevant technology based on this language is developing rapidly, the number of users is expanding rapidly, and the related resources are very large.
Although Python may be roughly categorized as a "scripting language" (script language), some large-scale software development programs such as Zope, Mnet and BitTorrent, Google, and Facebook, are also widely used. Python advocates prefer to call it a high-level dynamic programming language, because "scripting language" refers to a language that is simple programming tasks, such as Shell script, JavaScript, and other programming languages that can only handle simple tasks, and cannot be compared to Python.
In addition, because of Python's good support for C + + and other languages, many people also use Python as a "glue language" (glue language).

Implementation:
/sbin/grub-install/dev/sda
and then reboot.
