I'm trying to get a frequency distribution of a set of documents using Python. My code isn't working for some reason and is producing this error: <pre><code>Traceback (most recent call last): File "C:\Documents and Settings\aschein\Desktop\freqdist", line 32, in <module> fd = FreqDist(corpus_text) File "C:\Python26\lib\site-packages\nltk\probability.py", line 104, in __init__ self.update(samples) File "C:\Python26\lib\site-packages\nltk\probability.py", line 472, in update self.inc(sample, count=count) File "C:\Python26\lib\site-packages\nltk\probability.py", line 120, in inc self[sample] = self.get(sample,0) + count TypeError: unhashable type: 'list' </code></pre> Can you help? This is the code so far: <pre><code>import os import nltk from nltk.probability import FreqDist #The stop=words list stopwords_doc = open("C:\\Documents and Settings\\aschein\\My Documents\\stopwords.txt").read() stopwords_list = stopwords_doc.split() stopwords = nltk.Text(stopwords_list) corpus = [] #Directory of documents directory = "C:\\Documents and Settings\\aschein\\My Documents\\comments" listing = os.listdir(directory) #Append all documents in directory into a single 'document' (list) for doc in listing: doc_name = "C:\\Documents and Settings\\aschein\\My Documents\\comments\\" + doc input = open(doc_name).read() input = input.split() corpus.append(input) #Turn list into Text form for NLTK corpus_text = nltk.Text(corpus) #Remove stop-words for w in corpus_text: if w in stopwords: corpus_text.remove(w) fd = FreqDist(corpus_text) </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
