python-Excel读取-合并单元格读取

python-Excel读取-合并单元格读取（后续会补充python-Excel写入的部分）

1. python读取Excel单元格

代码包含读取Excel中数据，以及出现横向合并单元格，以及竖向合并单元格的内容。英文注释标注了函数的功能，后又补充了部分中文注释。

合并单元格的函数通用，可以直接复制拿走，传入的参数为Excel某sheet表中的数据。

两个列表合并为一个字典函数list_dic(list1,list2)也可以直接复制拿走，传入的参数为两个列表，list1准备作为key，list2准备作为value，key和value位置一一对应。
