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。

apply_dic = []
def get_excel():
with xlrd.open_workbook(r'D:\0325.xlsx') as workbook :
name_sheets = workbook.sheet_names() #获取Excel的sheet表列表,存储是sheet表名
for index in name_sheets: #for 循环读取每一个sheet表的内容
sheet_info = workbook.sheet_by_name(index) #根据表名获取表中的所有内容,sheet_info也是列表,列表中的值是每个单元格里值
first_line = sheet_info.row_values(0) #获取首行,我这里的首行是表头,我打算用表头作为字典的key,每一行数据对应表头的value,每一行组成一个字典
values_merge_cell = merge_cell(sheet_info) #这里是调用处理合并单元格的函数
for i in range(1, sheet_info.nrows): #开始为组成字典准备数据
other_line = sheet_info.row_values(i)
for key in values_merge_cell.keys():
if key[0] == i:
other_line[key[1]] = values_merge_cell[key]
#print(other_line)
dic = list_dic(first_line,other_line) #调用组合字典的函数,传入key和value,字典生成
apply_dic.append(dic)
