你的代码中存在一个问题，即在第15行中，你将 `id` 变量赋值为一个列表，而不是单个链接。因此，你需要将其改为 `id[i]`：

url_1 = 'https://www.4399.com' + id[i]

另外，你也需要将 `csv_writer.writerow(dit)` 放在 for 循环外面，否则你在每次循环中都会写入一行，导致重复写入。

下面是修改后的代码：

import requests
from lxml import etree
import csv

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36'
}

f = open('4399益智副本2.csv', mode='w', encoding='utf-8-sig', newline='')
csv_writer = csv.DictWriter(f, fieldnames=['游戏地址', '游戏名称'])
csv_writer.writeheader()

for i in range(1, 124):
    if i == 1:
        url = 'https://www.4399.com/flash_fl/5_1.htm'
    else:
        url = 'https://www.4399.com/flash_fl/more_5_{}.htm'.format(str(i))

    html = requests.get(url, headers=headers).content
    doc = etree.HTML(html)

    id = doc.xpath('//*[@id="classic"]/li/a/@href')
    name = doc.xpath('//*[@id="classic"]/li/a/text()')

    data_list = []
    for i in range(len(name)):
        dit = {}
        dit['游戏地址'] = 'https://www.4399.com' + id[i]
        dit['游戏名称'] = name[i]
        data_list.append(dit)

    csv_writer.writerows(data_list)

    print(data_list)

f.close()

import requests from lxml import etree import csv headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36' } f = open('益智地址.csv', mode='w', encoding='utf-8-sig', newline='') csv_writer = csv.DictWriter(f, fieldnames=[ '游戏地址']) csv_writer.writeheader() for i in range(1,123): if i == 1: url = 'https://www.4399.com/flash_fl/5_1.htm' html = requests.get(url,headers=headers).content doc = etree.HTML(html) url_1 = doc.xpath('//*[@class="list affix cf"]/li/a/@href') for i in range(len(name)): dit = {} new_url = 'https://www.4399.com' + url_1[i] for id in new_url: dit['游戏地址'] = id csv_writer.writerow(dit) else: url = 'https://www.4399.com/flash_fl/more_5_{}.htm'.format(str(i)) html = requests.get(url,headers=headers).content doc = etree.HTML(html) url_1 = doc.xpath('//*[@class="list affix cf"]/li/a/@href') for i in range(len(name)): dit = {} new_url = 'https://www.4399.com' + url_1[i] for id in new_url: dit['游戏地址'] = id csv_writer.writerow(dit) print(id)

这段代码是用来爬取4399网站上益智游戏的地址，并将其保存为csv文件的。具体来说，代码使用了requests库获取网页内容，使用lxml库解析HTML代码，然后使用csv库将获取到的数据保存为csv文件。其中，代码使用了循环来遍历所有分页，并且使用了字典来保存每个游戏的地址。不过，需要注意的是，在第一个循环中，使用了一个变量name来作为循环遍历的范围，但是这个变量并没有在代码中定义，可能会导致错误。
