python3 操作Excel文件

项目中经常用到读写Excel的功能,之前用Java写过一个. 但感觉还是太繁琐, 尤其是需要增加点功能的时间, 还得开一个工程(比如Eclipse)写代码, 编译, 导出jar文件. 然后才能使用. 最近发现用python读取起来更方便快捷一些.

直接改代码, 改完就能测.

我是用python3来做的这个工程, 当然python2也没问题, 而且因为第三方库的问题, 对python2的支持可能会更好一些. 个人习惯, 这里选择了python3

首先安装python3 下载地址

再下载两个需要的第三方库

xlrd https://pypi.python.org/pypi/xlrd 两个python版本都支持

xlwt https://pypi.python.org/pypi/xlwt3 仅是python3版本的库

安装方法, 参考库里面的Readme.html 或者Readme.txt

然后可以写功能代码了.

一个简单的功能, 把多个Excel表中的Sheet合并成一个. 这在实际项目中经常用到

#coding=utf-8

import os
import xdrlib, sys
import xlrd
import xlwt3 as xlwt

StringExcelSource = "./tables/string_语言包.xls"
StringExcelTarget = "./tables/string_final.xls"

RowIndex_Data = 3

#单元格内容转为字符串
def getText(value):
if(type(value) == float):
return str(int(value))
return str(value)

def open_excel(p_file):
try:
data = xlrd.open_workbook(p_file)
return data
except Exception as ex:
print (str(ex))

def makeSheetHead(p_excelSheetTarget):
l_excelSheetTarget.write(0, 0, "键")
l_excelSheetTarget.write(0, 1, "说明")
l_excelSheetTarget.write(0, 2, "英文")
l_excelSheetTarget.write(0, 3, "中文")
l_excelSheetTarget.write(1, 0, "id")
l_excelSheetTarget.write(1, 1, "des")
l_excelSheetTarget.write(1, 2, "en")
l_excelSheetTarget.write(1, 3, "cn")
l_excelSheetTarget.write(2, 0, "client")
l_excelSheetTarget.write(2, 1, "N")
l_excelSheetTarget.write(2, 2, "client")
l_excelSheetTarget.write(2, 3, "client")

if __name__ == "__main__":
print ("make string_final excel file ")

l_excelDataTarget = xlwt.Workbook()
l_excelSheetTarget = l_excelDataTarget.add_sheet("dict_string")
makeSheetHead(l_excelSheetTarget)

l_rowIndexTarget = RowIndex_Data

l_excelData = open_excel(StringExcelSource)
for l_sheet in l_excelData.sheets():
if(l_sheet.name.startswith("string_")):
#每一行数据进行遍历
for l_rowIndex in range(RowIndex_Data, l_sheet.nrows):
l_cellId = l_sheet.cell(l_rowIndex, 0).value
l_cellId = getText(l_cellId)
if (len(l_cellId) <= 0):
continue
for l_colIndex in range(0, l_sheet.ncols):
l_excelSheetTarget.write(l_rowIndexTarget, l_colIndex, l_sheet.cell(l_rowIndex, l_colIndex).value)
l_rowIndexTarget += 1

l_excelDataTarget.save(StringExcelTarget)

编译, 问题出现了.

Traceback (most recent call last):

它的解决方法有点怪,找到这个文件, (因为python版本问题, 和MacOs版本问题, 可能有出入)

/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/xlwt3/formula.py

#__slots__ = ["__init__",  "__s", "__parser", "__sheet_refs", "__xcall_refs"]
#>=-Rct-=<
__slots__ = ["__s", "__parser", "__sheet_refs", "__xcall_refs"]

这样修改一下就ok了.

以上记录, 以备忘!
