原 Excel 文件中的偶数行替换成对应上下两行的平均值

实现代码

python 复制代码

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) / 2
                avg_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

python 复制代码

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)
