运用Python 读写 Excel

下载第三方包xlrd

pip install xlrd
easy_install xlrd

安装完毕后，分析下面代码

from xlrd import open_workbook

wb = open_workbook('simple.xls','rb')
for s in wb.sheets():
    print 'Sheet:',s.name
    for row in range(s.nrows):
        values=[]
        for col in range(s.ncols):
            values.append(s.cell(row,col).value)
        print ",".join(values)
    print

wb为表格的对象

sheets()列表形式获取sheet1、sheet2、sheet3...

s代表sheet的对象，

其中s.nrows属性代表sheet的总行数

s.ncols属性代表sheet的总列数

s.cell(x,y)方法代表某一个单元格，其中x是具体的行数，y是具体的列数，可以获取到一个单元的对象

s.cell(x,y).value  .value属性可以获取到单元坐标内的值

 

写xls

from tempfile import TemporaryFile
from xlwt import Workbook

book = Workbook()
sheet1 = book.add_sheet('Sheet 1')
book.add_sheet('Sheet 2')
sheet1.write(0,0,'A1')
sheet1.write(0,1,'B1')

row1 = sheet1.row(1)
row1.write(0,'A2')
row1.write(1,'B2')

sheet1.col(0).width = 10000

sheet2 = book.get_sheet(1)
sheet2.row(0).write(0,'Sheet 2 A1')
sheet2.row(0).write(1,'Sheet 2 B1')
sheet2.flush_row_data()

sheet2.write(1,0,'Sheet 2 A3')
sheet2.col(0).width = 5000
sheet2.col(0).hidden = True

book.save('simple2.xls')
book.save(TemporaryFile())
