python PrettyTable模块的安装与简单应用

prettytable 是一款很简洁但是功能强大的第三方模块，主要是将输入的数据转化为格式化的形式来输出，即：以表格的形式的打印输出出来，能够起到美观的效果，今天简单地试用了一下，

一、下载与安装

进入pypi.python.org查找并下载prettytable将其放在python文件夹下的scripts文件夹下

进入命令提示符工具，转到scripts文件夹下，通过命令pip install prettytable-0.7.2.tar.bz2安装该模块

二、简单的使用

导入该模块

from prettytable import prettytable

创建表头

table=prettytable(["姓名","学号","性别"])

插入数据

table.add_row(["小明","01","男"])
table.add_row(["小红","02","女"])
table.add_row(["小黄","03","男"])

显示该表

print(table)

三、下面是具体的实践：

#!usr/bin/env python
#encoding:utf-8
