python对Excel表格操作

操作场景，给一个Excel表格随机生成10万个手机号码

python中常见的对Excel操作模块

xlwt module 将数据写入Excel表

xlrd module 读取Excel表格

xlsxwriter modole  xlwt模块的升级版，用于处理大量数据

先用xlwt写入Excel操作

import xlwt # 将数据写入Excel
import random

book = xlwt.Workbook(encoding=‘utf-8‘,style_compression=0) # 创建workbook对象，设置编码格式
worksheet = book.add_sheet(‘test‘,cell_overwrite_ok=True) # 创建一个sheet对象，cell_overwrite_ok表示可以覆盖单元格
worksheet.write(0,0,‘phone‘) # 在0,0位置写入phone，前面0代表列，后面0代表行

# 手机开头号码
prelist = ["130","131","132","133","134","135","136","137","138","139","147","150","151","152","153","155","156","157","158","159","186","187","188"]
nums = 0
for i in range(100000):
    # 组合成一个11位手机号码
    phones = random.choice(prelist)+"".join(random.choice("0123456789") for i in range(8))
    nums += 1
    worksheet.write(nums,0,phones)

book.save(r‘D:\python\test.xls‘)

执行后发现报错：ValueError: row index was 65536, not allowed by .xls format

原因是xlwt修改xls数据最多只能修改到65536行，所以只能使用新的模块xlsxwriter模块修改的文件是xlsx

用xlsxwriter模块修改Excel文件

import xlwt # 将数据写入Excel
import xlrd # 读取Excel文档
from xlutils.copy import copy
import xlsxwriter
import random

workbook = xlsxwriter.Workbook(r‘D:\python\test.xlsx‘) # 创建Excel文件
worksheet = workbook.add_worksheet() # 创建一个sheet，不加名字默认sheet
worksheet.write(0,0,"phone")
# 手机开头号码
prelist = ["130","131","132","133","134","135","136","137","138","139","147","150","151","152","153","155","156","157","158","159","186","187","188"]
nums = 0
for i in range(100000):
    # 组合成一个11位手机号码
    phones = random.choice(prelist)+"".join(random.choice("0123456789") for i in range(8))
    nums += 1
    worksheet.write(nums,0,phones)

workbook.close()
