Word Index
Write a python program that reads the contents of a text file. The program should create a dictionary in
which the key-value pairs are described as follows:
Key. The keys are the individual words found in the file.
576
Values. Each value is a list that contains the line numbers in the file where the word (the
key) is found.
For example, suppose the word “robot” is found in lines 7, 18, 94, and 138. The dictionary
would contain an element in which the key was the string “robot”, and the value was a list
containing the numbers 7, 18, 94, and 138.
Once the dictionary is built, the program should create another text file, known as a word index,
listing the contents of the dictionary. The word index file should contain an alphabetical listing
of the words that are stored as keys in the dictionary, along with the line numbers where the
words appear in the original file. Figure 9-1 shows an example of an original text file
(Kennedy.txt) and its index file (index.txt
