无法将图像src从html传递到request.get函数中

Question

我目前正在创建图像抓取工具，以从IMDB搜索结果中提取缩略图。我能够隔离特定.jpg的URL，但无法将响应对象传递给get函数。

# Essential variables and databases

repository = []
search_results = []


# Function to itemize URL search parameters

def source_identity():
 valid_input = False
 while not valid_input:
   try:

     source = Path(input("Please enter a file path: "))
     valid_input = True

     for files in os.listdir(source):
         repository.append(str(files))

    except FileNotFoundError as err: print(err) + source_identity()



def image_search():
 try:
  if repository:
     search_url = ("http://www.imdb.com/find?ref_=nv_sr_fn&q=" + 
 str(repository[0].replace(" ","+").replace("(","").replace(")","") + 
 "&s=all"))
     data = requests.get(search_url)
     data.raise_for_status()


     search_targets = open("search_targets.txt", "wb")
     for chunk in data.iter_content(100000):
         search_targets.write(chunk)
     print(search_url)
     soup = bs4.BeautifulSoup(data.text, "html.parser")
     thumbnail = soup.select(".primary_photo a:nth-of-type(1)")
     print(thumbnail)
     if  not thumbnail:
         return "Could not find image"
     else:
         for p in thumbnail:
             y = [tag["src"] for tag in p.findAll("img")]
             print(type(y))
             print(y)

             img_url = "http:" + str(thumbnail[0].get(str(y)))
             print("Downloading image %s..." % img_url)
             res = requests.get(img_url)
             res.raise_for_status()
  else:
     return print("in return")
 except FileExistsError as err:
     print(err) + image_search()
 except Exception as err:
     print(err)

此输出：

    Please enter a file path: D:\Movies
    http://www.imdb.com/find?ref_=nv_sr_fn&q=2+Guns+2013&s=all
    <class 'list'> 'https://m.mediaamazon.com/images/M/MV5BNTQ5MTgzNDg4OF5BMl5BanBnXkFtZTcwMjAyODEzOQ@@._V1_UX32_CR0,0,32,44_AL_.jpg'

我尝试了几种提取src url的方法，并不断提出各种我无法解决的错误
