Part 1: How complex is the language used in the text? Create a folder for HW 3. Download the zip file hw3Files.zip from Piazza. Put it in this folder and unzip it. You should see a file named syllables.py which will be a helper module for this homework. Write your program in the same folder as this file and name it hw3Part1.py A few things to get familiar with before solving this part. In this part, you must get familiar with a function called split) that takes a piece of text, and converts it to a list of strings. Here is an example run: > line "Citadel Morning Nevs. Nevs about the Citadel in the porning, pretty selr explanatory ['Citadel, 'Morning Nevs. w aboatthe Citadel', 'ia', 'the. corning,'pretty'elf explanatory.' You will also need to use the function find nun syllables) from the file sy11ables.py which takes as input an English word as a string and that returns the total number of syllables in that word as an integer. The module works even if the word has punctuation symbols, so you do not need to remove those explicitly. Make sure you import this module appropriately into your program findu syllablea("coapater) >> find nus ayllables("acience") >> find_nnsyllables("introduction") Clearly, the second result is incorreet. The module we provided is not a perfect implementation of syllable counting, so you may find errors. It is not your job to fix them, use the module as it is, with errors and all. Do not worry about the mistakes it makes. To properly compute this, we would need to use a Natural Language Processing (NLP) module like NLTK, which we have not installed in this course. 3 5 0 Part 1: How complex is the language used in the text?
