前提知识：
测试数据：
安装 ：pip install openpyxl
读取from openpyxl import load_workbook
# 导入excel文件
workbook = load_workbook(filename='test.xlsx’)
或
workbook = open("test.xlsx")
# 打印该文件所有表名
print(workbook.sheetnames)
# 切换表
sheet = workbook['sheet1']
# 打印该表单元格规模
print(sheet.dimensions)
# 取该表的某个单元格
cell = sheet['A1']
# 打印该单元格的坐标
print(cell.row, cell.column, cell.coordinate)
# 获取多个单元格
for cell in sheet['A1:A10']
for cell in sheet['A1:G10']
for rows in sheet.iter_rows(min_row=1,max_row=5,min_col=2,max_col=7):
for cell in rows:
print(cell.value,end='')
print()
# 获取单元格对象的值,[必须是单元格对象]，如果取到元组是点不出value的
print(cell.value)
写入
# 保存
workbook.save('test.xlsx')
# 修改
cell = sheet['A1']
cell.value = 'A1'
# 追加到最后最后一行
sheet.append([15, None, None, 14, 'qq.com'])
# 添加公式
sheet['K11'] = '=AVERAGE(K1:K10)'
# 在第二行处增加4行
sheet.insert_rows(2,4)
# 在第二列处增加4列
sheet.insert_cols(2,4)
# 删除行
sheet.delete_rows(2,4)
# 删除列
sheet.delete_cols(2,4)
# 最后一定要保存一遍
workbook.save('test.xlsx')
# 创建excel
from openpyxl import Workbook
workbook = Workbook()
