NLTK python error: "TypeError: 'dict_keys' object is not subscriptable"
I am using python 3.5
and I meet the same problem of TypeError
.
Using vocab = list(fdist1.keys())
does not give me the top 50 most frequently used words.
But fdist1.most_common(50)
does.
Further,if you just want to show those top 50 words not with their frequency,you can try :
[word for (word, freq) in fdist1.most_common(50)]
Looks like you are using Python 3. In Python 3 dict.keys()
returns an iterable but not indexable object. The most simple (but not so efficient) solution would be:
vocab = list(fdist1.keys())[:200]
In some situations it is desirable to continue working with an iterator object instead of a list. This can be done with itertools.islice()
:
import itertools
vocal_iterator = itertools.islice(fdist1.keys(), 200)
