I'm trying to extract US states from wiki URL, and for which I'm using Python Pandas. 

```
import pandas as pd
import html5lib
f_states = pd.read_html('https://simple.wikipedia.org/wiki/List_of_U.S._states') 

```

However, the above code is giving me an error L

> 
> ImportError Traceback (most recent call last)

I installed html5lib and beautifulsoup4 as well, but it is not working. 
Can someone help pls.
