python如何读写EXCEL文档 (有助于自动化的参数化，用的方法是XLRD，XLWT）

读EXCEL：

import xlrd

例1，

data=xlrd.open("E:egg.xls")     # 打开xls文件

table=data.sheets()[0]             # 打开第一张表

nrows=table.nrows                   # 获取表的行数

for i in range(nrows)

print table.row_values(i)[:7]       # 取前7行的值

例2：

import xlrd

#打开一个workbook

workbook = xlrd.open_workbook('E:\Code\Python\testdata.xls')

#抓取所有sheet页的名称

worksheets = workbook.sheet_names()

print('worksheets is %s' %worksheets)

#定位到sheet1

worksheet1 = workbook.sheet_by_name(u'Sheet1')

"""

#通过索引顺序获取

worksheet1 = workbook.sheets()[0]

#或

worksheet1 = workbook.sheet_by_index(0)

#遍历所有sheet对象

for worksheet_name in worksheets:

worksheet = workbook.sheet_by_name(worksheet_name)

#遍历sheet1中所有行row

num_rows = worksheet1.nrows

for curr_row in range(num_rows):

row = worksheet1.row_values(curr_row)

print('row%s is %s' %(curr_row,row))

#遍历sheet1中所有列col

num_cols = worksheet1.ncols

for curr_col in range(num_cols):

col = worksheet1.col_values(curr_col)

print('col%s is %s' %(curr_col,col))

#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

写EXCEL：

import xlwt

例1：

#创建workbook和sheet对象

workbook=xlwt.Workbook()          #注意Workbook的开头W要大写

sheet1=workbook.add_sheet("sheet1")

sheet2=workbook.add_sheet(sheet2")

#向sheet页中写入数据

sheet1.write(0,0,"aaaaaa")

sheet2.write(0,0,"bbbbb")

#保存该excel文件,有同名文件时直接覆盖

workbook.save("E:egg.xls")

print "ok"
