A simple code question...

Asked 2 years ago, Updated 2 years ago, 83 views

I am Parin who is learning Python in many ways.

There is one program that is currently in use There is a part that I want to modify, but it doesn't work out well, so I'm asking you

First of all, this is the program code currently in use. As you can see from the bottom of the result, if you enter the URL you want, you can extract the PATH of the image file It's a program, currently from the results specified below

Image:External URL for https://c1.staticflickr.com/5/4005/34867024234_53b7383815_s.jpg Because of this, starting from https, it displays the entire URL.

The program code currently in use.


def scraper(link):
    res = requests.get(link)

    for image in BeautifulSoup(res.text, 'html.parser', parse_only=SoupStrainer('img')):
        src = image.get('src')
        print('Image: ' + str(src))


def create_parser():
    parser = argparse.ArgumentParser()
    parser.add_argument('link', help='url of page to scrape')
    return parser


def main(args):
    parser = create_parser()
    args = parser.parse_args(args)
    url = args.link
    return scraper(url)


if __name__ == '__main__':
    main(sys.argv[1:])

Result value

Please refer to the following.

import requests, bs4

_url = 'http://www.kldp.org'

content = requests.get(_url).content
imgs = bs4.BeautifulSoup(content, 'html.parser', parse_only=bs4.SoupStrainer('img'))
img_urls = (img['src'] if img['src'].startswith('http') else f"{_url}{img['src']}"forimgin imgs) # Add request url if the start of image url is not http.

for url in img_urls: print(url)
