How to do it...

It's impossible to remember which characters are invalid and manually escape them with percent signs, but the built-in Python module urllib.parse has the required methods to solve this.

Now we can try fixing this by escaping/URL encoding the request. Rewrite the script as follows:

patten = '(http)?s?:?(\/\/[^"]*\.(?:png|jpg|jpeg|gif|png|svg))' 
for line in open('packtpub.txt'): 
    for m in re.findall(patten, line): 
        print('https:' + m[1]) 
        fileName = basename(urllib.parse.urlsplit(m[1])[2]) 
        print(fileName) 
        request = 'https:' + urllib.parse.quote(m[1]) 
        img = urllib.request.urlopen(request).read() 
        file = open(fileName, "wb") 
        file.write(img) 
        file.close()  
        break
