Bulk download images from specific URLs with python

Introduction

In the previously written "Download images from a specific site URL in bulk with python", for example

<img src="../sample.png ">

This time, I fixed the problem that the image could not be downloaded due to ERROR. However, this program is basically root on the url? I'm thinking of a case where it is divided on (http: // domain name / hierarchy). (I'm pretty poor at explaining and I don't understand what I'm saying (^^;) ↑)

Added code

What I added in this code is a function called get_url_root. Arguments: url entered by the user Return value: url up to the domain name. If the return value is 0, it means ERROR.

python

def get_url_root(url):
    if("http://" in url):
        url_delet_http = url.lstrip("http://")
        if("/" in url_delet_http):
            url_root = "http://" + url_delet_http[0:url_delet_http.find("/")]
            return url_root
    elif("https://" in url):
        url_delet_https = url.lstrip("https://")
        if("/" in url_delet_http):
            url_root = "http://" + url_delet_http[0:url_delet_http.find("/")]
            return url_root
    return 0

Edited code

Finally, the part where you actually download the image. If the url contains " ../ ", use the above function to get the url up to the domain name and For example, change the .. part of ../sample.png to http://sample.com/sample.png.

python

for j in range(0,(len_url-1)):
        url = number_url[j]
        if("../" in url):
            root_url = get_url_root(serch_url)
            if(root_url!=0):
                url = url.replace("..",root_url)
                print url
                download(url)
        else:
            download(url)
