Python3操作Excel文件(读写)的简单实例

投稿:daisy

这篇文章主要给大家介绍了关于Python3操作Excel文件(读写)的相关资料,文中通过示例代码介绍的非常详细,对大家学习或者使用Python3具有一定的参考学习价值,需要的朋友们下面来一起学习学习吧

安装

pip install xlrd,还能更简单点吗?

使用参考:xlrd官网

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()。

读取Excel:

from mmap import mmap, ACCESS_READ
from xlrd import open_workbook

testxls = './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_TEXT

book = 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_workbook

book = 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)

Writing Excel Files(写Excel文件)

一个Excel文件的构成包含:

  1. Workbook 就当作是Excel文件本身了
  2. Worksheets 就是sheet
  3. Rows 每个sheet的行
  4. Columns 每个sheet的列
  5. 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,支持Python3.X,用法据说与xlwt模块一模一样

pip install xlwt-future 装起来。

A Simple Example(一个简单的写xls文件例子)

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