excel保存数据的三种方式：

 1、pandas保存excel数据，后缀名为xlsx;

  举例：       

import pandas as pd

dic = {
    '姓名': ['张三', '李四', '王五', '赵六'],
    '年龄': ['18', '19', '20', '21'],
    '住址': ['广州', '青岛', '南京', '重庆']
}
dic_file = pd.DataFrame(dic)
dic_file.to_excel('2.xlsx', index=False)

2、openpyxl保存excel数据，后缀名为xlsx；

---------A、覆盖数据-----------
from openpyxl import Workbook  
# 1、创建工作簿
wb = Workbook()

# 确定某一张表  
sheet = wb.active

# 2、数据读写
info_list = [
    ['姓名', '年龄', '性别'],
    ['张三', '19', '男'],
    ['李四', '20', '女'],
    ['王五', '21', '女']
]
for info in info_list:
    sheet.append(info)

sheet.append(['tom', '12', '女'])

# 3、保存
wb.save('2.xlsx')

-----------B、追加数据---------
from openpyxl import load_workbook

wb = load_workbook('2.xlsx')

sheet.append(['王五', '21', '女'])

sheet.save('2.xlsx')

3、xlutils保存excel数据，后缀名为xls【使用模版代码】。xlutils是一个库，它是一个成品案

使用步骤：

（1）构造一个字典，如 data = { '表名': ['张三', '18', '本科'] }

（2）复制成品代码

（3）调用保存函数

（4）修改某些内容 【表头 文件名xls 表名=键】

（5）复制导包
