如何从csv中拆分八位字节的ip地址

import csv

def split_ip_from_csv(csv_file):
    ip_addresses = []
    
    with open(csv_file, 'r') as file:
        reader = csv.reader(file)
        header = next(reader)  # 跳过标题行
        
        ip_column_index = header.index('IP地址')  # 假设IP地址列标题为'IP地址'
        
        for row in reader:
            ip_address = row[ip_column_index]
            ip_bytes = ip_address.split('.')  # 使用'.'分割IP地址
            
            # 将IP地址的四个八位字节转换为整数，并存储在列表中
            ip_bytes = [int(byte) for byte in ip_bytes]
            ip_addresses.append(ip_bytes)
    
    return ip_addresses

# 示例用法
csv_file = 'data.csv'
ip_addresses = split_ip_from_csv(csv_file)
print(ip_addresses)
