python excel的操作

1、在测试用例中生成的数据报错到已存在的excel里面

 1 import xlrd
 2 from xlutils.copy import copy
 3 class test:
 4     def write_data_into_excel(self, file_path, data_list):
 5         wk = xlrd.open_workbook(file_path)
 6         workbook = copy(wk)   # a writable copy (I can't read values out of this, only write to it)
 7         s = workbook.get_sheet(0)
 8         s.write(0, 0, data_list[0])    # 写入第一行第一列
 9         s.write(0, 1, data_list[1])    # 写入第一行第二列
10         workbook.save(file_path)    

2、把excel中的某个单元格的值删除（等价于把这个单元格的值赋值为空值）

 import xlrd
 from xlutils.copy import copy
 class test:
     def delete_excel_value(self, file_path):
         wk = xlrd.open_workbook(file_path)
         workbook = copy(wk)
         s = workbook.get_sheet(0)
         s.write(0, 0, '')
         s.write(0, 1, '')
         workbook.save(file_path)
         print("Delete finished.")

3、读取全部单元格的值

 import xlrd
 class test:
     def get_excel_column(self, file_path):
         workbook = xlrd.open_workbook(file_path)
         sheet = workbook.sheet_by_name('Sheet1')
         clo_num = sheet.ncols  # 获取列数
         row_num = sheet.nrows  # 获取行数
         data_list = []
         i = 0
         if i in range(row_num):
             data_list.append(sheet.row_values(i))
         return data_list
