Excel file deletes data in rows and saves it

At this stage, it is implemented by code, and the data is deleted every four lines

import pandas as pd
# 读取 Excel 文件
excel_file = 'xxxx.xlsx'
df = pd.read_excel(excel_file)

rows_to_keep = []
# 要删除的行数
skip_rows = 4  
for i, row in enumerate(df.iterrows()):
    index, data = row
    if i % (skip_rows + 1) == 0:
        rows_to_keep.append(index)

# 保留需要的行
filtered_df = df.loc[rows_to_keep]

# 将结果保存到新的 Excel 文件
output_excel_file = 'xxxx.xlsx'  # 替换为你想要保存的 Excel 文件路径
filtered_df.to_excel(output_excel_file, index=False)
print("成功")
