Concord University Python Dictionary Structure Project Lab Report
Assignment #10
This assignment uses a great deal of text. We will focus on the Python dictionary structure which you worked on in module 10. We will use data based on an online copyright free version of Roget’s thesaurus on Gutenberg: http://www.gutenberg.org/cache/epub/10681/pg10681.txt – you can download a copy of the thesauraus here: python_asg10_Roget_Thesaurus.txt
Part 0
You have been hired by a small software company to create a “thesaurus” program that replaces words with their synonyms. The company has set you up with a sample thesaurus stored in a Python dictionary object. Here’s the code that represents the thesaurus:
# define our simple thesaurus
thesaurus = {
"happy": "glad",
"sad" : "bleak"
}
The dictionary contains two keys – “happy” and “sad”. Each of these keys holds a single synonym for that key.
Write a program that asks the user for a phrase. Then compare the words in that phrase to the keys in the thesaurus. If the key can be found you should replace the original word with the synonym for that word. Words that are changed in this way should be printed in UPPERCASE letters. Make sure to remove all punctuation from your initial phrase so that you can find all possible matches. Here’s a sample running of your program:
Enter a phrase: Happy Birthday! exclaimed the sad, sad kitten GLAD birthday exclaimed the BLEAK BLEAK kitten
Part 1
Your company realizes that they probably need more than one synonym for each word, so they updated your thesaurus accordingly:
# define our simple thesaurus
thesaurus = {
"happy":["glad", "blissful", "ecstatic", "at ease"],
"sad" :["bleak", "blue", "depressed"]
}
The dictionary contains two keys – “happy” and “sad”. Each of these keys holds a list that contains synonyms of that key.
Write a program that asks the user for a phrase. Then compare the words in that phrase to the keys in the thesaurus. If the key can be found you should replace the original word with a random synonym for that word. Words that are changed in this way should be printed in UPPERCASE letters. Here’s a sample running of your program:
Enter a phrase: Happy Birthday! exclaimed the sad, sad kitten ECSTATIC birthday exclaimed the DEPRESSED BLEAK kitten
Part 2
The 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 (the file is included in the downloadable data files above – the filename for the thesaurus is “python_asg10_Roget_Thesaurus.txt“).
word1,synonym1,synonym2,...,synonymN-1,synonymN word2,synonym1,synonym2,...,synonymN-1,synonymN word3,synonym1,synonym2,...,synonymN-1,synonymN
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:
Total words in thesaurus: 33054 Enter a phrase: happy birthday said the sad kitten CONTENT ANNUAL HOLIDAY PRONOUNCED the DOLOROUS CHESHIRE CAT
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.
Part 3
Your program is a hit! In fact, some famous recording artists have come to you to help them re-write some of their most popular songs so that they aren’t so “repetitive”. Your first customer is Mr. Justin Bieber, who’s hit song “Baby” needs a little bit of work:
The lyrics to this song is stored in a text file named “bieber_baby.txt” which you can download here: bieber_baby.txt
Justin doesn’t want you to change ALL of his lyrics – just a few here and there to add some variety. Begin by asking the user for a “chance” value – this value dictates the % chance that a given word will be substituted with one in the thesaurus. Finally, open the file and swap out words using the “chance” value supplied (i.e. the word is “happy” and the chance is 0.5 – this word is in the thesauraus, so there is a 50% chance that we would swap it with a random word from the thesaurus and a 50% chance that we will leave it as-is). Words that are swapped should be printed in all UPPERCASE letters. Here’s a sample running of your program (note that you can simply remove all puntuation from the source file for this program):
Total words in thesaurus: 33054 Enter a % chance to change a word: 0.5 oh whoa oh whoa oh whoa you know you REGARD me i know ETHICAL SELF care just shout whenever and ill be there you are my love you are my INNER NATURE and we will NOT A BIT IN ANY WAY ever be RETIRED are we an INSTANCE SUBTEENER ABJURE WAGERING were just friends what are you TEACHING say theres another and look right in my eyes my INAUGURAL YOUNG MAN DEAD my heart for the first MARCH TEMPO and i was IN KIND LAMBKIN baby TOMATO oooh DOTE ON baby DAMSEL baby nooo PHONY FLEDGLING baby baby oooh i thought youd INFLEXIBLY GO ON mine HOPEFUL YOUNGER SWEETKINS oooh UXORIOUSNESS baby COMPACT DOTE nooo AFTER THIS FASHION INVERTEBRATE baby DIMINUTIVE oooh i ADVERTENCY youd ALL ALONG SUBSIST EXCAVATE oh IN THAT you i would have THROUGH WITH whatever and i UNINFLUENCED cant SENSE we aint together and i wanna play it DIMINISH but im losin you SINFUL HOLD WITH you anything ill buy you ANYTHING COCKPIT and im in pieces LOVER STABILIZE me and just shake SUBCONSCIOUS SELF til SUBLIMINAL SELF TAILPIECE OTHER SELF from this bad dream im RELEASE GROUND down down down and i UNPREPOSSESSED cant ALLOW my COMMENCEMENT ADORATION wont OCCUR NEAR ENOUGH TO and im CLOSE COPY RECRUIT baby baby oooh RIVAL baby DRY-NURSE baby nooo IN THAT WAY baby YEARLING PRECIOUS HEART oooh i thought youd EVER AND ANON OCCUR mine GAL FLAME baby oooh like baby baby baby nooo like baby DUCKLING baby oooh i SYMPATHY youd DAILY AND HOURLY BE MET WITH FIRETRAP luda JUST THE SAME i was i had my first WANT there was nobody that compared to my baby and nobody came between us or could ever come ABOVE AND BEYOND she had me SOMATIC DEATH crazy oh i was starstruck she woke me up daily dont DEPRIVATION DECIDING VOTE starbucks FEMALE BEING made my heart pound I MYSELF skipped a beat ALTHOUGH i see MY HUMBLE SELF in the PAVED ROAD and at VIEW on the playground but i EXACTLY wanna see her on the PUT IN TIME she knows she got me dazing cause she was STRAIGHT amazing and ADVANCED my heart is breaking ENTIRELY i BARELY THE HOLE WHEREBY NOTE baby baby baby oooh AT WHAT PRICE baby baby baby nooo CHICKEN LIVER SISSY baby PONY oooh i IDEATIVE youd RAPIDLY HOLD CONVERT WEANLING DEBUTANT JELLYFISH oooh AT PAR baby SUBDEB baby nooo CLOSE NEONATAL baby SCHOOLMAID oooh i thought youd always BE THE CASE mine im ASLEEP yeah yeah yeah yeah yeah yeah THIS NIGHT im INTEGRATED gone yeah yeah yeah yeah yeah yeah IN THESE DAYS im all IMBECILE yeah yeah yeah yeah yeah yeah now im BODILY IMBECILE gone gone gone im FLABBY
