经验证，python 3.4.3下可用。请各位朋友明察。

 

 

使用Python操作Excel不是什么难事，需要用到两个Lib， python-xlrd，python-xlwt

安装

pip install xlrd xlwt
支持xls，xlsx格式

写Excel

创建一个文件
workbook = xlwt.Workbook(encoding='utf-8')
增加一个表单
booksheet = workbook.add_sheet('Sheet 1')
增加一行
row = booksheet.row(i)
增加一列
col = booksheet.col(j)
为某个单元格赋值
booksheet.write(i, j, 'Test')
row.write(j, 'Test')
col.write(i, 'Test')
注意: 在add_sheet时, 置参数cell_overwrite_ok=True, 可以覆盖原单元格中数据。
cell_overwrite_ok默认为False, 覆盖的话, 会抛出异常.

import xlwt
workbook = xlwt.Workbook(encoding='utf-8')
booksheet = workbook.add_sheet('Sheet 1', cell_overwrite_ok=True)
workbook.add_sheet('Sheet 2')
DATA = (('学号', '姓名', '年龄', '性别', '成绩'),
             (1001, 'AAAA', 23, '男', 98),
             (1002, 'BBBB', 21, '女', 90),
             (1003, 'CCCC', 24, '女', 100),
             (1004, 'DDDD', 22, '女', 86),
             (1005, 'EEEE', 25, '女', 88),)

for i, row in enumerate(DATA):
    for j, col in enumerate(row):
        booksheet.write(i, j, col)
booksheet.col(0).width=10
workbook.save('成绩单.xls')

 

读Excel

获取一个文件
workbook = xlrd.open_workbook('成绩单.xls')
获取文件中表单数量
workbook.nsheets
获取一个表单
workbook.sheets()[i],
workbook.sheet_by_index(i)
workbook.sheet_by_name(u'Sheet1')
获取行，列数
sheet.nrows, sheet.ncols
获取整行，列数据
sheet.row(i), sheet.col(j)
获取某个单元格数据
sheet.cell(i, j).value
sheet.row(i)[j].value
sheet.col(j)[i].value

import xlrd
workbook = xlrd.open_workbook('成绩单.xls')
print("There are {} sheets in the workbook".format(workbook.nsheets))
for booksheet in workbook.sheets():
    print(booksheet.name)
    for row in range(booksheet.nrows):
        for col in range(booksheet.ncols):
            print(xlrd.cellname(row, col))
            print(booksheet.cell(row, col).value)
