爬取优美图库壁纸-python

爬取216页分块区所有图片，爬的内容有点抽象。说实在的这网站壁纸挺檫边的.....

import requests
from bs4 import BeautifulSoup
import os

# 创建目录
directory = 'pictures'
url = ''
if not os.path.exists(directory):
    os.makedirs(directory)
for i in range(216):
    if i == 0:
        url = 'https://www.umei.cc/meinvtupian/meinvxiezhen/'
    elif i >= 2:
        #爬取网站源码
        url = 'https://www.umei.cc/meinvtupian/meinvxiezhen/' + 'index_{}'.format(i) + '.htm'

    resp = requests.get(url)
    resp.encoding = 'utf-8'
    # print(resp.text)
    #解析html
    main_page = BeautifulSoup(resp.text,"html.parser")
    #找
    step1 = main_page.find("div",class_="listlbc_cont_l").find_all("div",class_="item masonry_brick")

    #子网页网址
    url_new = ''

    index = 0
    step2 = []

    for a in step1:
        step2 = a.find_all("a")[0]
        url_new = 'https://www.umei.cc' + step2.get("href")
        #子网页寻找
        resp1 = requests.get(url_new)
        resp1.encoding = 'utf-8'
        #解析
        next_page = BeautifulSoup(resp1.text,'html.parser')
        #找
        step3 = next_page.find("div",class_="wrapper").find("div",class_="big-pic").find("a").find("img").get("src")
        print(step3)
        with open(os.path.join(directory, f"{index}.jpg"),mode='wb') as f:
            get_pictures = requests.get(step3).content
            f.write(get_pictures)
            index += 1
