python-user-agents library is not working
Question: I am trying to use the [python-user-agents](https://github.com/selwin/python-
user-agents/blob/master/user_agents/parsers.py). I keep running into a number
of bugs within the library itself.

First it referred to a `from ua_parser import user_agent_parser` that it never
defined. So after banging my head, I looked online to see what that might be
and found that `ua_parser` is yet another library that this project was using.
So I downloaded `ua_parser`. But now I am getting an error that

    
    
    TypeError: parse_device() got an unexpected keyword argument 'model'
    

Sure enough, `ua_parser` has a model variable that the python-user-agents
library is not expecting. Has anyone done a better job with this library?
Whoever wrote it clearly did a terrible job. But it seems to be the only thing
out there that I could find. Any help fixing it to work well? I am looking to
use it so to identify if a browser's device is mobile or touchable or a tablet
as in: `user_agent.is_mobile` or `user_agent.is_touch_capable` or
`user_agent.is_tablet`


Answer: if you look at the readme from the github link it tells you what to install
and how to use the lib:

You need pyyaml and ua-parser:

    
    
    pip install pyyaml ua-parser user-agents
    

A working example:

    
    
    In [1]: from user_agents import parse
    
    In [2]: ua_string = 'Mozilla/5.0 (iPhone; CPU iPhone OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B179 Safari/7534.48.3'
    
    In [3]: user_agent = parse(ua_string)
    
    In [4]: user_agent.is_mobile
    Out[4]: True
    
    In [5]: user_agent.is_touch_capable 
    Out[5]: True
    
    In [6]: user_agent.is_tablet
    Out[6]: False
