Python3操作Excel文件（读写）的简单实例

读Excel文件通过模块xlrd 写Excel文件同过模块xlwt(可惜的是只支持Python2.3到Python2.7版本) xlwt-future模块支持Python3.X用法据说与xlwt模块一模一样 Excel2007往后版本多了一个xlsx文件类型运城网站优化用法据说与xlwt模块一模一样 Excel2007往后版本多了一个xlsx文件类型是为了使Excel能存入超过65535行数据（1048576）所以读写xlsx文件需要另一个库叫openpyxl网站优化怎么弄所以读写xlsx文件需要另一个库叫openpyxl支持Python3.x

pip install xlrd还能更简单点吗？

安装的版本为0.9.3但是官网的介绍还是关于Version 0.7.3版本的无妨不影响理解。

Tutorial PDF指向的API url也404了不怕我们还有help()。

from mmap import mmap, ACCESS_READfrom xlrd import open_workbooktestxls = './剩余工作LIST.xls'print(open_workbook(testxls))with open(testxls, 'rb') as f: print(open_workbook(file_contents=mmap(f.fileno(),0,access=ACCESS_READ)))wb = open_workbook(testxls)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(str(values)))

Getting a particular Cell（获取特定的Cell）

from xlrd import open_workbook,XL_CELL_TEXTbook = open_workbook(testxls)sheet = book.sheet_by_index(0)# cell = sheet.cell(0,0)# print(cell)# print(cell.value)# print(cell.ctype==XL_CELL_TEXT)for i in range(sheet.ncols): print (sheet.cell_type(1,i),sheet.cell_value(1,i))

Iterating over the contents of a Sheet(迭代Sheet中的内容)

from xlrd import open_workbookbook = open_workbook(testxls)sheet0 = book.sheet_by_index(0)sheet1 = book.sheet_by_index(1)print(sheet0.row(0))print(sheet0.col(0))print(sheet0.row_slice(0,1))print(sheet0.row_slice(0,1,2))print(sheet0.row_values(0,1))print(sheet0.row_values(0,1,2))print(sheet0.row_types(0,1))print(sheet0.row_types(0,1,2))print(sheet1.col_slice(0,1))print(sheet0.col_slice(0,1,2))print(sheet1.col_values(0,1))print(sheet0.col_values(0,1,2))print(sheet1.col_types(0,1))print(sheet0.col_types(0,1,2))

Types of Cell（cell的类型）

Text: 对应常量 xlrd.XL_CELL_TEXT Number: 对应常量 xlrd.XL_CELL_NUMBER Date：对应常量 xlrd.XL_CELL_DATE NB: 数据并非真正存在于Excel文件中 Boolean: 对应常量 xlrd.XL_CELL_BOOLEAN ERROR: 对应常量 xlrd.XL_CELL_ERROR Empty / Blank: 对应常来 xlrd.XL_CELL_EMPTY 等等等等…… balabala总之是Excel有啥就有啥

Writing Excel Files（写Excel文件）

一个Excel文件的构成包含：

Workbook 就当作是Excel文件本身了 Worksheets 就是sheet Rows 每个sheet的行 Columns 每个sheet的列 Cells sheet上的每个独立块

不幸的是xlwt不支持python3.X版本。Library to create spreadsheet files compatible with MS Excel 97/2000/XP/2003 XLS files, on any platform, with Python 2.3 to 2.7。 万幸的是有一个xlwt-future模块网站优化怎么弄我们还有help()。

读取Excel：

pip install xlwt-future 装起来。

A Simple Example（一个简单的写xls文件例子）

from tempfile import TemporaryFilefrom xlwt import Workbookbook = 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 = 10000sheet2 = 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 = 5000sheet2.col(0).hidden = Truebook.save('simple.xls')book.save(TemporaryFile())
