#!/usr/bin/env python3

import os, bs4, sys, requests

try:
        os.mkdir('Downloaded_Images')
except FileExistsError:
        print('Saving files to Downloaded_Images folder')

for i in range(50):
        # What to search
        url_part_1 = "https://www.google.com/search?safe=strict&hl=en&site=imghp&tbm=isch&source=hp&biw$
        url_part_2 = "#imgrc=Ek3sgIvXh3zzZM%3A"
        image_to_search = sys.argv[1]
        search = url_part_1 + image_to_search + url_part_2

        # Issue GET request and download search page
        responce = requests.get(search)
        responce.raise_for_status()
        soup = bs4.BeautifulSoup(responce.text, "html.parser")

        # Locate the images
        picture_element = soup.select('a img')
        if picture_element == []:
                print('Could not locate images something went wrong')
        else:
                picture_location = picture_element[i].get('src')
                print('Downloading ' + str(i))
                responce = requests.get(picture_location)
                responce.raise_for_status()
                image_file = open(os.path.join('Downloaded_Images', os.path.basename('image_' + str(i))$
                for chunk in responce.iter_content(100000):
                        image_file.write(chunk)
                image_file.close()

以下是我运行它的代码./google_images_downloader.py what_you_wanna_search。但是，如果你注意到它在范围内表示我（50）。这是问题，它不下载50个图像只有19.它只下载19无论搜索。我究竟做错了什么？我收到了错误

picture_location = picture_element [i] .get（＆＃39; src＆＃39;） IndexError：列表索引超出范围

但是当我检查元素时，它看起来像picture_element = soup.select（＆＃39;一个img＆＃39;）是对的。谢谢你的帮助！

程序不使用Beautiful Soup
