Python批量自动下载获取图片

import requests

urlshu = 1      #url中first = urlshu
pictureshu = 1  #图片下载时的名字（加上异常图片的第几张图片）
soupshu = 0     #每35张soup列表中第soupshu个
whileshu = 35   #用于while循环的数（因为每个页面35张图片）

    }
#有35张图片的网页的请求标头

            pictureshu -= 1
            ifopen = 0      #取消下载此图片，否则会一直卡着然后报错
    while ifopen == 1:
        text = open('%s/'%content + '%d'%pictureshu + '.jpg','wb')  #将图片下载至文件夹'图片'中
        text.write(picture)     #上行代码中'wb'为写入二进制数据
        text.close()
        ifopen = 0
        number = number - 1
        
    pictureshu = pictureshu + 1
    soupshu = soupshu + 1
    whileshu = whileshu - 1
    
    if whileshu == 0:   #第一页图片下载完成，将网址的first进1
        urlshu = urlshu + 1
        whileshu = 35
        soupshu = 0
        
    if number == 0:     #下载图片数量达标，退出循环
        print("查找完成")
        break

会自动生成你想搜索的这个东西的目录，非常方便，同时会自动批量编号。
