　　In [1]: print "hello world"
　　hello world
　　In [2]: import platform
　　In [3]: print platform.       （无法使用tab补全）
　　ipython环境下按tab键、删除键
　　需要安装python模块setuptools和readline模块
　　
　　1.安装 setuptools
　　安装pip首先下载安装  setuptools-0.6c11.tar ,
　　tar xf setuptools-0.6c11.tar
　　cd setuptools-0.6c11
　　python setup.py  build
　　python setup.py  install
　　
　　2.安装readline
　　pip install readline
　　或者：
　　下载readline模块
　　https://pypi.python.org/packages/source/r/readline/readline-6.2.4.1.tar.gz#md5=578237939c81fdbc2c8334d168b17907
　　tar xf readline-6.2.4.1.tar.gz#md5\=578237939c81fdbc2c8334d168b17907.gz
　　python setup.py install
