最近学习爬虫，可是代码出来之后效果很不对劲，有大神看看出了什么问题，谢谢了……

Question

import requests
from bs4 import BeautifulSoup

url = 'https://699pic.com/qingnianshenghuo.html'

resp = requests.get(url)
resp.encoding='utf-8'

main_page= BeautifulSoup(resp.text, 'html.parser')

alist = main_page.find_all("div", class_="photo-tag")
child_href_list=[]
for a in alist:


    w=a.find("a")

    hrefs = "https:"+w.get("href")
    child_href_list.append(hrefs)
    
    for href in child_href_list:
        child_page_resp = requests.get(href)
        child_page_resp.encoding="utf_8"
        child_page_text = child_page_resp.text
        child_page=BeautifulSoup(child_page_text,"html.parser")
        p = child_page.find("a", class_="photo-img-link")

        img = p.find("img")



        print("https:"+img.get("src"))

主要是抓取的图片重复的太厉害，尤其是第一张图片，没有规律的循环重复……

Answer 1

for href in child_href_list:
        child_page_resp = requests.get(href)
        child_page_resp.encoding="utf_8"
        child_page_text = child_page_resp.text
        child_page=BeautifulSoup(child_page_text,"html.parser")
        p = child_page.find("a", class_="photo-img-link")

        img = p.find("img")



        print("https:"+img.get("src"))

这段代码不要放到for a in alist:循环里，提到外面就可以了
