python之openpyxl模块的安装和基本用法（excel管理）

pip3 install openpyx

import openpyxl
wb = openpyxl.Workbook('Book1.xlsx')
wb1 = openpyxl.load_workbook('Book2.xlsx')

print(wb)
print(type(wb))
print(wb1)
print(type(wb1))

import openpyxl

wb = openpyxl.load_workbook('Book2.xlsx')
print(wb.sheetnames)
print(wb.active)
print(wb.worksheets)
print(wb.read_only)
print(wb.encoding)
print(wb.properties) ##运行结果最后三行属于该属性

import openpyxl

wb = openpyxl.load_workbook('Book2.xlsx')
##选择要操作的工作表， 返回工作表对象
sheet = wb['排序商品信息']
#获取工作表的名称
print(sheet.title)
# 获取工作表中行和列的最值
print(sheet.max_column)
print(sheet.max_row)
print(sheet.min_column)
print(sheet.min_row)
##修改表的名称
sheet.title = 'sheet1'
print(sheet.title)
# 返回指定行指定列的单元格信息
print(sheet.cell(row=1, column=2).value)
cell = sheet['B1']
print(cell)
print(cell.row, cell.column, cell.value,cell.coordinate)

##选择要操作的工作表， 返回工作表对象

 # 循环遍历每一个单元格
 for cell in row:
