Get a sum in python dictionary
<p>I got a dictionary like from my code</p>

<pre><code>city = place_user['full_name'].encode("utf-8").split('full_name')
city_point = dict.fromkeys(city, sum)
# the result is below:
{'Los Angeles': 30}
{'Batu Ceper' : 20}
{'Ocean Acres': 10}
{'Los Angeles': 20} 
</code></pre>

<p>I want to get result which item has the biggest point in dictionary.
The result like this:</p>

<pre><code>Lo(or LA): 50
</code></pre>

<p>I'd like to abbreviate item like LA or Lo(first two characters). </p>

<p>How do I write a code in simple way? </p>
