python之excel读写操作

Posted 2020-12-24 $he_ding%

一、xlrd和xlwt安装

1、下载xlwt安装包https://pypi.org/project/xlwt/#files

2、解压后进入文件目录

3、执行python setup.py install

二、读取操作

 1 # -*- conding:utf-8 -*-
 2 __author__ = ‘dsh‘
 3 # How to read from an Excel using xlrd module
 4 import xlrd
 5 # 关联指定路径中的xls文件，得到book对象
 6 file_name = "name.xls"
 7 #打开指定文件，创建文件对象
 8 book = xlrd.open_workbook(file_name)
 9 # 通过sheet索引获得sheet对象
10 sheet1 = book.sheet_by_index(0)
11 # # 获得指定索引的sheet名
12 # sheet1_name = book.sheet_names()[0]
13 # print(sheet1_name)
14 # # 通过sheet名字获得sheet对象
15 # sheet1 = book.sheet_by_name(sheet1_name)
16 # 获得行数和列数
17 # 总行数
18 nrows = sheet1.nrows
19 #总列数
20 ncols = sheet1.ncols
21 # 遍历打印表中的内容
22 for i in range(nrows):
23   for j in range(ncols):
24     cell_value = sheet1.cell_value(i, j)
25     print(cell_value, end = "	")
26   print("")

三、写入操作

 1 # -*- conding:utf-8 -*-
 2 __author__ = ‘dsh‘
 3 #How to write to an Excel using xlwt module
 4 import xlwt
 5 #创建一个Wordbook对象，相当于创建了一个Excel文件
 6 book = xlwt.Workbook(encoding = "utf-8", style_compression = 0)
 7 #创建一个sheet对象，一个sheet对象对应Excel文件中的一张表格
 8 sheet = book.add_sheet("sheet1", cell_overwrite_ok = True)
 9 #向表sheet1中添加数据
10 sheet.write(0, 0, "EnglishName") #其中，"0, 0"指定表中的单元格，"EnglishName"是向该单元格中写入的内容
11 sheet.write(1, 0, "MaYi")
12 sheet.write(0, 1, "中文名字")
13 sheet.write(1, 1, "蚂蚁")
14 #最后，将以上操作保存到指定的Excel文件中
15 book.save("name.xls")

四、实名制文档格式转换读写案例

#!/usr/bin/python
# -*- coding: utf-8 -*-
import xlrd
import xlwt
import sys
import os

__author__ = ‘dsh‘

file_name = "1111.xls"
book_read = xlrd.open_workbook(file_name)
sheet_read = book_read.sheet_by_index(0)
nrows_read = sheet_read.nrows
ncols_read = sheet_read.ncols

book_write = xlwt.Workbook(encoding = "utf-8",style_compression = 0)
sheet_write = book_write.add_sheet("sheet1",cell_overwrite_ok = True)

#把第0列写到第1列
for i in range(nrows_read):
    cell_value = sheet_read.cell_value(i,0)
    sheet_write.write(i,1,cell_value)

#把第10列数据写到第3列
for i in range(nrows_read):
    cell_value = sheet_read.cell_value(i,10)
    sheet_write.write(i,3,cell_value)

book_write.save("2222.xls")
