[b][color=green][size=large]我们都知道在JAVA里，我们可以使用POI来操作Excel文件，在POI的API里有HSSFWorkbook支持03版的excel的读写，有XSSFWorkbook是针对07以后的excel文件的读写，那么在python3.x（散仙使用的版本是python3.4）里，我们应该如何操作excel。

首先在python3.4里，我们可以使用新的python类库，来支持3.x之后的读写excel

针对 03版excel（xls结尾的），我们可以使用xlrd读，xlwt包来写
针对 07版excel（xlsx结尾的）,我们可以使用openpyxl来操作读写excel

xlwt的下载地址[url]https://pypi.python.org/pypi/xlwt3[/url]
xlrd的下载地址[url]https://pypi.python.org/pypi/xlrd3[/url]
openpyx1的下载地址[url]https://pypi.python.org/pypi/openpyxl[/url]

下载完扩展的包库之后，直接解压某个目录，然后执行命令进行安装包系统的python类库里：

python setup.py install

[b][color=green][size=large]核心代码，如下所示：[/size][/color][/b]

#读取excel使用(支持03)
import xlrd
#写入excel使用(支持03)
import xlwt3
#读取execel使用(支持07)
from openpyxl import Workbook
#写入excel使用(支持07)
from openpyxl import load_workbook

[b][color=olive][size=large]最后，分享三个格式数字和日期，以及随机数生成3个小知识点[/size][/color][/b]

#浮点数格式化成百分比
pp="{:.1%}".format(0.2356)
print(pp)

#格式化日期
import  datetime
s=(2014,12,11,0,0,0)
d="%02d-%02d-%02d" % s[:3]
print(d)

#打印随机数
import random
#浮点数随机数
f=random.uniform(1.0,100)
#整数范围随机数
f1=random.randint(1,23)
print(f1)
print(f)
