Working with unicode keys in a python dictionary

Question

I am learning about the Twitter API using Python 2.7.x. I\'ve saved a number of random tweets and I am trying to process them. Each tweet is converted to a dictionary with j

Answer 1

Python 2 handles translation between str and unicode keys transparently for you, provided the text can be encoded to ASCII:

>>> d = {u'text': u'Foo'}
>>> d.keys()
[u'text']
>>> 'text' in d
True
>>> u'text' in d
True
>>> d['text']
u'Foo'
>>> d[u'text']
u'Foo'

This means that if you get a KeyError for tweet['text'], then that dictionary has no such key.
