This is my python code. 

```
r = requests.get("myurl")
data = r.text
soup = BeautifulSoup(data, "lxml")
texttmp = ""
for link in soup.find_all('a'):
    image = link.get("href")
    if ".jpg" in image:
        print(image)

```

When I try to run this code, I am getting below error. How can I fix this?

```
