Lab Haiku

Lab - Haiku Checker 

 

Background

Haiku's are a form of Japanese poetry.  They consist of 3 lines of text.  The first line of the haiku must contain 5 syllables.  The second line must have 7 syllables.  Finally, the third line again contains 5 syllables.

Here is an example of a valid haiku:

An old silent pond

A frog jumps into the pond—

Splash! Silence again.

by Matsuo Basho

 

Objectives

• Practice if-else and conditionals.
• Practice with functions
• Practice using a helper function
• Practice with loops
• More practice with lists

Program the Solution

Write a program called haiku_checker.py that contains two functions.

The first function will be a helper function that is called check_n_syllables.  This function must take input of a list of words on a line and an int number of syllables to validate.  You may use the pysyllables library to make this easier https://pypi.org/project/pysyllables/. You will need to install the pysyllables  package through the Thonny package manager. Make sure you also do an import at the top of your file:

from pysyllables import get_syllable_count

You can then use the get_syllable_count(word) function to get the number of syllables in a word.

The return value of the function should be as follows:

• This function should return either a -1 if the total syllables is less than the given number n to validate,
• 0 if the total syllables is equal to the number n,
• and 1 if the total syllables is greater than n.

The second function should be called validate_haiku.  It will take a single parameter of a list of lists. The list will contain 3 lines for the haiku.  Each line will be a sub list of the words in the line. The function will return a String value. 

The return values should follow these rules:

• It should be set to "Valid haiku." if this is a valid haiku that has a first line with 5 syllables, second line with 7 syllables, and third line with 5 syllables. 
• If it has more or less than 3 lines it should return: "Invalid haiku, not 3 lines.". 
• Otherwise it will return a message with the type of error for each line.  For example: if the first line has 7 syllables it would return: "Line 1 too short. "[note the space after the period].  If the second line has 3 syllables it would return "Line 2 too short. ".  If the third line is too long it would return: "Line 3 too long. ". 

Your program should allow multiple comments, for instance 1 for each line that is wrong.  The overall message should be on a single line of output.  Do not return an error if a line is valid.  Note: You should have a return at the end of each error message and only return one continuous String with all error messages as the final return String.
