print("The number of worksheets is {0}".format(book.nsheets))
print("Worksheet name(s): {0}".format(book.sheet_names()))
sh = book.sheet_by_index(0)
print("{0} {1} {2}".format(sh.name, sh.nrows, sh.ncols))
print("Cell B3 is {0}".format(sh.cell_value(rowx=2, colx=1)))
for rx in range(sh.nrows):
    print(sh.row(rx))

 

0x02 xlwt

用xlwt创建一个简单的.xls文件

import xlwt
from datetime import datetime

style0 = xlwt.easyxf('font: name Times New Roman, color-index red, bold on',
    num_format_str='#,##0.00')
style1 = xlwt.easyxf(num_format_str='YYYY-MM-DD HH:MM:SS')

wb = xlwt.Workbook()
ws = wb.add_sheet('A Test Sheet')

ws.write(0, 0, 1234.56, style0)
ws.write(1, 0, datetime.now(), style1)
ws.write(2, 0, 1)
ws.write(2, 1, 1)
ws.write(2, 2, xlwt.Formula("A3+B3"))

wb.save('example.xls')

 

0x03 xlutils

This package provides a collection of utilities for working with Excel files.
官方文档:https://xlutils.readthedocs.io/en/latest/api.html
github项目:https://github.com/python-excel/xlutils

安装:
(如果没安装xlrd、xlwt,会自动安装这2个模块)

pip install xlutils

使用:

import xlrd
import xlwt
import xlutils
import xlutils.copy as copy

rdbook = xlrd.open_workbook('first.xls')
wtbook = copy.copy(rdbook)
wtsheet = wtbook.get_sheet(0)
type(wtsheet)
wtsheet.write(0,0,'pcat.cc')
wtbook.save('second.xls')

 

0x04 openpyxl

A Python library to read/write Excel 2010 xlsx/xlsm files.
官方文档:https://openpyxl.readthedocs.io/en/stable/
安装:

pip install openpyxl

使用:
写xlsx文件

from openpyxl import Workbook
wb = Workbook()
# grab the active worksheet
ws = wb.active
# Data can be assigned directly to cells
ws['A1'] = 42
# Rows can also be appended
ws.append([1, 2, 3])
# Python types will automatically be converted
import datetime
ws['A2'] = datetime.datetime.now()
# Save the file
wb.save("sample.xlsx")

读xlsx文件

from openpyxl import load_workbook
wb = load_workbook(filename='pcat.xlsx')
sheet_ranges = wb['Sheet1']
print(sheet_ranges['A2'].value)

注意:
openpyxl不支持.xls格式。
读写文件前记得多备注,有时候可能有bug。
