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。

import xlrd
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)
            return apply_dic

def list_dic(list1,list2):

    merge = {}
    merge_cells = sheet_info.merged_cells
    for (rlow, rhigh, clow, chigh) in merge_cells:
        value_mg_cell = sheet_info.cell_value(rlow, clow)
        if rhigh-rlow == 1:
            # Merge transverse cells
            for n in range(chigh-clow-1):
                merge[(rlow, clow+n+1)] = value_mg_cell
        elif chigh-clow == 1:

                merge[(rlow+n+1, clow)] = value_mg_cell
    return merge
