Python库： PrettyTable 模块

一，PrettyTable简介

PrettyTable是python中的一个第三方库，可用来生成美观的ASCII格式的表格：

二，PrettyTable安装

使用PIP即可十分方便的安装PrettyTable，如下：

pip install prettytable

三，PrettyTable导入 

from prettytable import PrettyTable

四，PrettyTable使用： 

  创建表：

     tb = pt.PrettyTable（）

按行/列添加数据：

     tb.add_row（）

tb.add_column（）

GitHub上有详细示例说明，按行/列添加数据：

按行添加数据

... tb = pt.PrettyTable()

tb.field_names = ["City name", "Area", "Population", "Annual Rainfall"]

tb.add_row(["Adelaide",1295, 1158259, 600.5])

tb.add_row(["Brisbane",5905, 1857594, 1146.4])

tb.add_row(["Darwin", 112, 120900, 1714.7])

tb.add_row(["Hobart", 1357, 205556,619.5])

print(tb)

+-----------+------+------------+-----------------+

| City name | Area | Population | Annual Rainfall |

+-----------+------+------------+-----------------+

| Adelaide | 1295 | 1158259 | 600.5 |

| Brisbane | 5905 | 1857594 | 1146.4 |

| Darwin | 112 | 120900 | 1714.7 |

| Hobart | 1357 | 205556 | 619.5 |

+-----------+------+------------+-----------------+

按列添加数据

... tb.add_column('index',[1,2,3,4])

print(tb)

+-----------+------+------------+-----------------+-------+

| City name | Area | Population | Annual Rainfall | index |

+-----------+------+------------+-----------------+-------+

| Adelaide | 1295 | 1158259 | 600.5 | 1 |

| Brisbane | 5905 | 1857594 | 1146.4 | 2 |

| Darwin | 112 | 120900 | 1714.7 | 3 |

| Hobart | 1357 | 205556 | 619.5 | 4 |

+-----------+------+------------+-----------------+-------+
