computer science
Description
Part 1:
Write a program that opens a user-specified text file and then displays a list
of all the unique words found in the file. In the end include a count of how
many unique words were found. Remove punctuation. Use the attached
file to test your program; there are 138 unique words in the file.
Hint: Create a dictionary using the words in the file as keys. Before
adding a new key, use 'in' to determine if it is already in the dictionary.
Part 2:
Modify the program to count and display the frequency of each word.
Which word appears most often in the Gettysburg Address?
Hint: Use the value of each dictionary item to count the number of times
each word appears.
Four score and seven years ago our fathers brought forth on this continent a
new nation, conceived in liberty and dedicated to the proposition that all
men are created equal.
Now we are engaged in a great civil war, testing whether that nation or any
nation so conceived and so dedicated, can long endure. We are met on a great
battlefield of that war. We have come to dedicate a portion of that field, as
a final resting place for those who here gave their lives that that nation
might live. It is altogether fitting and proper that we should do this.
But, in a larger sense, we can not dedicate, we can not consecrate, we can
not hallow this ground. The brave men, living and dead, who struggled here,
have consecrated it, far above our poor power to add or detract. The world
will little note, nor long remember what we say here, but it can never forget
what they did here. It is for us the living, rather, to be dedicated here to
the unfinished work which they who fought here have thus far so nobly
advanced. It is rather for us to be here dedicated to the great task
remaining before us that from these honored dead we take increased devotion
to that cause for which they gave the last full measure of devotion; that we
here highly resolve that these dead shall not have died in vain; that this
nation, under God, shall have a new birth of freedom; and that government of
the people, by the people, for the people, shall not perish from the earth.
