第一行起始行是17 ， 也就是从导入包开始为第一行

问题相关代码，请勿粘贴截图

import urllib.request
from lxml import etree

def create_request(page):
    if (page == 1):
        url = 'https://sc.chinaz.com/tupian/qinglvtupian.html'
    else:
        url = 'https://sc.chinaz.com/tupian/qinglvtupian_' + str(page) + '.html'
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.5060.53 Safari/537.36 Edg/103.0.1264.37'
    }
    request = urllib.request.Request(url, headers=headers)
    return request

def get_content(request):
    response = urllib.request.urlopen(request)
    content = response.read().decode('utf-8')
    return content

def down_load(content):
    tree = etree.HTML(content)

    name_list = tree.xpath('//div[@id="container"]//a/img/@alt')

    # 一般网页的图片都会进行懒加载
    src_list = tree.xpath('//div[@id="container"]//a/img/@src2')

    for i in range(len(name_list)):
        name = name_list[i]
        src = src_list[i]
        url = 'https:' + src

        urllib.request.urlretrieve(url = url,filename='./loveImg' + name + '.jpg')


if __name__ == '__main__':
    start_page = int(input('请输入开始页码：'))
    end_page = int(input('请输入结束页码：'))

    for page in range(start_page,end_page+1):
        # (1)请求对象定制
        request = create_request(page)
        # (2)获取网页源码
        content = get_content(request)
        # (3)下载图片
        down_load(content)

运行结果及报错内容

请输入开始页码：1
请输入结束页码：5
Traceback (most recent call last):

    src = src_list[i]

我的解答思路和尝试过的方法

我想要达到的结果

Answer 1

你这两个列表中的元素长度不一样，然后循环的时候超出src_list的值了
