Python操作Excel

本文主要是介绍Python操作Excel，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

首先我们需要安装名为xlrd和xlwt这两个库，其中xlrd是读excel，xlwt是写excel的库

pip install xlrd

pip install xlwt

然后根据以下示例进行操作

读文件：

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
"""
#其他写法：
cell = worksheet1.cell(rown,coln).value
print cell
#或
cell = worksheet1.row(rown)[coln].value
print cell
#或
cell = worksheet1.col(coln)[rown].value
print cell
#获取单元格中值的类型，类型 0 empty,1 string, 2 number, 3 date, 4 boolean, 5 error
cell_type = worksheet1.cell_type(rown,coln)
print cell_type
写文件：

import xlwt wbk = xlwt.Workbook()

sheet = wbk.add_sheet('sheet 1')

sheet.write(0,1,'test text')#第0行第一列写入内容

wbk.save('test.xls')
