How to convert unicode to integer or float in dictionary in Python

Question

For example, I have a dictionary, which is like:

Degree = {'Union': u'1', 'Cook': u'3', 'Champaign': u'7'}

How can I convert it as:

Degree = {'Union': 1, 'Cook': 3, 'Champaign': 7}

I know it's not a hard question, but I try many methods, like json, *.items... but I just do not get it.

Have you tried `int`?! Why don't you show what you've tried and describe what the problem is? — jonrsharpe, Aug 02 '14 at 22:54
Yes, so add a loop. This isn't a code-writing service, read [the docs](https://docs.python.org/2/tutorial/datastructures.html#dictionaries). — jonrsharpe, Aug 02 '14 at 22:59
Yes, I know. Sorry about that. I also read this: http://stackoverflow.com/questions/1254454/fastest-way-to-convert-a-dicts-keys-values-from-unicode-to-str I tried... and still don't get it... — Wei-Ting Liao, Aug 02 '14 at 23:01

Use a dictionary comprehension:

converted_degrees = {key: int(value) for (key,value) in Degree.items()}
>>> converted_degrees
{'Union': 1, 'Cook': 3, 'Champagne': 7}

Thank you so so so much!!! It works now. I used to use for and if to distinguish the string and int then I failed many times. Again, Thank you so much. – Wei-Ting Liao Aug 02 '14 at 23:10

Use int(value) to convert it :

values = {k:int(v) for(k,v) in Degree.items()}
