[Python] execl读写

相关库

读:xlrd

写:xlwt

案例

要求:

将图1中的数据导以图2的形式写入另一个文件中

第一列索引关系:{1:K1-B1,2:K1-B2}

。。。(18列)

思路:

按行读取数据,根据索引关系按列写入数据

代码:

 1 import xlrd
 2 import xlwt
 3 #柱号映射关系
 4 index = ['K1-B1','K1-B2']
 5 load_cnt = 6
 6 #读excel文件
 7 wb = xlrd.open_workbook(r'C:UsersAdministratorDesktopdemo111.xls')
 8 sheet1 = wb.sheet_by_index(0)
 9 index_col = sheet1.col_values(0)[1:]
10 joint_cnt = len(index_col)
11 #写excel文件
12 f = xlwt.Workbook()
13 sheet2 = f.add_sheet(u'sheet1',cell_overwrite_ok=True)
14 for i in range(joint_cnt):
15     for j in range(joint_cnt):
16         if index_col[j] == index[i]: break
17     target_row = sheet1.row_values(j+1)[1:]
18     num_cnt = len(target_row)
19     for k in range(load_cnt):        
20         sheet2.write(3*i,k,target_row[3*k])
21         sheet2.write(3*i+1,k,target_row[3*k+1])
22         sheet2.write(3*i+2,k,target_row[3*k+2])
23 f.save(r'C:UsersAdministratorDesktopdemo222.xls')
