  • ipython的用法详解

    ipython是一个升级版的交互式python命令行工具.

    ipython安装

    pip install ipython

    等到命令执行完成后显示successfully表示完装成功

    在命令提示符下输入ipython就可以启动ipython了

    其与原版python命令行工具不同在于ipython的提示符变成了in和out.

    in为输入命令的地方,out为命令执行完成后输出的地方

     

    ipython的特点

    tab键自动补全一些常用的方法

    支持一些系统命令

        In [2]: pwd             # 显示当前所在目录
        Out[2]: '/root'
        
        In [3]: cd ..           # 返回当前目录的上一级目录
        /   
       

    执行系统命令(!)
