python-操作excel、csv数据文件

1、excel文件操作

# -*- coding: utf-8 -*-
import  xlrd
workbook = xlrd.open_workbook(‘D:\\workspace\\eclipse-python\\test\\myexcel.xls‘)
sheetname=workbook.sheet_names()#抓取所有sheet页的名称
print ‘myexcel is ‘,sheetname[0],sheetname[1],sheetname[2]

#定位到sheet1
worksheet1=workbook.sheet_by_name(u‘【工作月报】‘)

#遍历sheet1中所有行row
num_rows=worksheet1.nrows
print u‘总行数=‘,num_rows

for i in range(num_rows):
    row=worksheet1.row_values(i)
    print u‘获取的第‘,i,u‘行的数据是‘,row[0],row[1],row[2]
#遍历sheet1中所有列col
num_cols=worksheet1.ncols
print u‘总列数=‘,num_cols

for j in range(num_cols):
    col=worksheet1.col_values(j)
    print u‘获取的第‘,i,u‘列的数据是‘,col[0],col[1],col[2],col[3],col[4]

#遍历sheet1中所有单元格cell
for rown in range(num_rows):
    for coln in range(num_cols):
        cell = worksheet1.cell_value(rown,coln)
        print cell
