I have downloaded Beautifulsoup and want to import it in my python program. I have typed my python program as below:

```
import urllib
from BeautifulSoup import *
url = raw_input('Enter - ')
html = urllib.urlopen(url).read()
soup = BeautifulSoup(html)
tags = soup('a')
for tag in tags:
    print 'TAG:',tag
    print 'URL:',tag.get('href', None)
    print 'Contents:',tag.contents[0]
    print 'Attrs:',tag.attrs

```

Now i have saved it in a different folder.
When i try running the program, i get the following error.

![error message](https://i.stack.imgur.com/01DOf.png) 

So, what could be the reason for this and how can I make it work?
Thanks in advance !
I'm using Python 2.7.13 and will **import** work in it?
i tried importing **bs4** and it gave **import is not recognized as an internal or external command**
