Summary     : An interpreted, interactive, object-oriented programming language

Description :

Python is an interpreted, interactive, object-oriented programming

language often compared to Tcl, Perl, Scheme or Java. Python includes

modules, classes, exceptions, very high level dynamic data types and

dynamic typing. Python supports interfaces to many system calls and

libraries, as well as to various windowing systems (X11, Motif, Tk,

Mac and MFC).

Programmers can write new built-in modules for Python in C or C++.

Python can be used as an extension language for applications that need

a programmable interface. This package contains most of the standard

Python modules, as well as modules for interfacing to the Tix widget

set for Tk and RPM.

Note that documentation for Python is provided in the python-docs

package.

重复安装？？？

要解决上述问题，可以这样:

# 首先安装 yum-utils 套件

　　
　　yum install yum-utils

　　

# 执行 clean duplicate package

　　

　　package-cleanup --cleandupes

  Duplicate Package Options:

    --dupes             Scan for duplicates in your rpmdb

    --cleandupes        Scan for duplicates in your rpmdb and remove older

    --noscripts         disable rpm scriptlets from running when cleaning

                        duplicates
