pythone函数基础（11）读，写，修改EXCEL

#读EXCEL需要导入xlrd模块---在python控制台pip install xlrd模块
import xlrd
book = xlrd.open_workbook('stu3.xls')
sheet = book.sheet_by_index(0)
# sheet = book.sheet_by_name('sheet1')
# print(sheet.cell(0,0).value)#获取指定单元格的内容
# print(sheet.cell(1,0).value)
# print(sheet.row_values(0)) #获取整行的数据
# print(sheet.row_values(1))
# print(sheet.col_values(0))#获取整列的数据
# print(sheet.col_values(1))

print(sheet.nrows) #行数
print(sheet.ncols) #列数
for row in range(1,sheet.nrows):
    print(sheet.row_values(row))

写EXCEL需要导入 import xlwt -----在python控制台pip install xlwt模块

import xlwt
book = xlwt.Workbook() #新建一个excel
sheet = book.add_sheet('sheet1') #添加一个sheet页

# sheet.write(0,0,'编号')
# sheet.write(0,1,'名字')
# sheet.write(0,2,'性别')
#
# sheet.write(1,0,'1')
# sheet.write(1,1,'马春波')
# sheet.write(1,2,'男')

stu_info  = [
    ['编号','姓名','密码','性别','地址'],
    [1,'machunbo','sdfsd23sdfsdf2','男','北京'],
    [2,'machunbo2','sdfsd23sdfsdf2','男','北京'],
    [3,'machunb3','sdfsd23sdfsdf2','男','北京'],
    [4,'machunbo4','sdfsd23sdfsdf2','男','北京'],
    [5,'machunbo5','sdfsd23sdfsdf2','男','北京'],
    [6,'machunbo6','sdfsd23sdfsdf2','男','北京'],
    [7,'machunbo6','sdfsd23sdfsdf2','男','北京'],
    [8,'machunbo6','sdfsd23sdfsdf2','男','北京'],
    [9,'machunbo6','sdfsd23sdfsdf2','男','北京'],
    [10,'machunbo6','sdfsd23sdfsdf2','男','北京'],
    [11,'machunbo6','sdfsd23sdfsdf2','男','北京'],
]
#6行5列
# row = 0 #行
# for stu in stu_info:
#     sheet.write(row,0,stu[0])
#     sheet.write(row,1,stu[1])
#     sheet.write(row,2,stu[2])
#     sheet.write(row,3,stu[3])
#     sheet.write(row,4,stu[4])
#     row+=1

# row = 0 #行
# for stu in stu_info:
#     #stu
#     col = 0  # 列
#     # [1, 'machunbo', 'sdfsd23sdfsdf2', '男', '北京'],
#     for s in stu: #控制列
#         sheet.write(row,col,s) #0 3 男
#         col+=1
#     row+=1

for index,value in enumerate(stu_info):
    #  index 0
    # value ['编号','姓名','密码','性别','地址']

    #index 1
    #value [1,'machunbo','sdfsd23sdfsdf2','男','北京']
    for index2,v2 in enumerate(value):
        print(index,index2,v2)
        #0 1
        #1 machunbo
        #2 sdfsd23sdfsdf2
        #4 北京
        sheet.write(index,index2,v2)

book.save('stu3.xls')  #wps xls xlsx  ,微软的office  xls
修改EXCEL，需要import xlutils-----在python控制台pip install xlwt模块

import xlrd
from xlutils import copy

#1、先打开原来的excel
#2、复制一份
#3、在复制的excel上修改
#4、保存

book = xlrd.open_workbook('stu3.xls')
new_book = copy.copy(book) #
sheet = new_book.get_sheet(0) #修改excel的时候，得用get_sheet()
sheet.write(0,0,'id')
sheet.write(0,3,'password')
new_book.save('stu3.xls')
