Question

Using PythonThe company quickly realized that the simple two-word thesaurus was far too small. In order to address this shortcoming they have provided you with a very large text file that contains over 30,000 words.  Copy this text-only thesaurus and save it in a file named python_asg10_Roget_Thesaurus.txt.

Every word occupies its own line followed by a comma-separated list of synonyms. Every word can have a potentially unlimited # of synonyms. Your task for this part is to open this file and parse it into a Python dictionary object so that it functions just like the simple thesaurus from the previous part. Here's a sample running of your program:

Hint: For each word you will need to create a new list that contains all the synonyms for that word. You can then store this list in the dictionary using the word as the key.

Explanation / Answer

worddict = {}

#read file contents

## Open the file with read only permit
f = open('D:/ravi/Cheg/python_asg10_Roget_Thesaurus.txt', "r")

## use readlines to read all lines in the file

lines = f.readlines()

## close the file after reading the lines.
f.close()

#Parse each line

for str in lines:
#   print(str)
   tokens = str.split(",")
   count = 0
   key = tokens[0]
   worddict[key] = tokens[1:]
   print("Key : %s" %key)

print(worddict)

-----------------output------------------

Key : word1
Key : word2
Key : word3
{'word3': ['synonym1', 'synonym2', '...', 'synonymN-1', 'synonymN'], 'word1': ['synonym1', 'synonym2', '...', 'synonymN-1', 'synonymN '], 'word2': ['synonym1', 'synonym2', '...', 'synonymN-1', 'synonymN ']}
