python-excel

1. 字典转化为数组

   users=[{"id": "7972",
    "user_id": "17775207320",
   "con_pwd": "123456",
   "regist_time": "2018-07-27 08:28:50"}]
   table_head=list(users[0].keys())#取出所有的key值
   table_content=[]
   for user in users:
       table_content.append(list(user.values()))#把所有的value组成一个二维数组

2. python中的excel表，首先安装openpyxl

3. 写入数据

   from openpyxl in Workbook
   table_content=[
    ['a','b','c'],
   [1,2,3],
   [21,22,23],
   [31,32,33]
   ]
   
   #写入方法
   
   def sava_excel(filename,data):
       try:
           wb=Workbook()#新建excel文件
           sheet=wb.creat_sheet('Data',index=0)#新建一个工作薄，0表示第一个位置
           for row in data:
               sheet.append(row)
           wb.sava(filename)
       except Exception as ex:
           print(ex)
   sava_excel('myData.xlsx',table_content)

4. 读取excel中数据

   from openpyxl import Workbook
   from openpyxl import load_workbook
   try:
       workbook=load_workbook(u'myData.xlsx')
       #获得表单名字
       sheetname=workbook.get_sheet_names()
       my_sheet=workbook.get_sheet_by_name(sheetname[0])
       #获得一个单元格的内容
       A4=my_sheet['A4']
       print(A4.value)
       #文件中有多少行，多少列
       print(my_sheet.max_row)
       print(my_sheet.max_column)
       table_content=[]
       for row in my_sheet.rows:
           table_row=[]
               for cell in row:
                   table_row.append(cell.value)
           table_content.append(table_row)
       print(table_content)
       except Exception as ex:
           print(ex)
