实现代码

import openpyxl# 打开Excel文件
input_file = 'input.xlsx'
output_file = 'input3.xlsx'
wb = openpyxl.load_workbook(input_file)
output_wb = openpyxl.Workbook()# 处理每个工作表
for sheet_name in wb.sheetnames:sheet = wb[sheet_name]# 新建一个工作表，用于存储处理后的数据output_sheet = output_wb.create_sheet(title=sheet_name)# 处理数据for row in range(1, sheet.max_row+1):if row % 2 == 0:# 计算上下两行的平均值avg_values = []for col in range(1, sheet.max_column+1):avg_value = (sheet.cell(row=row-1, column=col).value + sheet.cell(row=row+1, column=col).value) / 2avg_values.append(avg_value)# 将平均值写入新行output_sheet.append(avg_values)else:# 直接将原数据写入新行row_values = []for col in range(1, sheet.max_column+1):row_values.append(sheet.cell(row=row, column=col).value)output_sheet.append(row_values)# 保存新Excel文件
output_wb.save(output_file)

补充:取出excel的奇数行

import openpyxl# 打开Excel文件
input_file = 'input.xlsx'
output_file = 'output.xlsx'
wb = openpyxl.load_workbook(input_file)
output_wb = openpyxl.Workbook()# 选择需要处理的sheet
sheet = wb.active# 选择需要提取的行数
rows_to_extract = []
for i in range(1, sheet.max_row+1):if i % 2 == 1: # 只提取奇数行rows_to_extract.append(i)# 处理数据
output_sheet = output_wb.active
for row_num, row in enumerate(sheet.iter_rows(values_only=True), start=1):if row_num in rows_to_extract:output_sheet.append(row)# 保存新Excel文件
output_wb.save(output_file)
