Question

Using python

Question 13 (20 points) Write a function named Linestats that finds the number of consonant and vowel letters on each line of a file and writes those statistics to a corresponding line of a new file, separated by a space. Definitions: A vowel letter is one of a, e, i, o, u, along with the corresponding uppercase letters..A consonant letter is not a vowel letter. The function linestats takes two parameters: 1. inFile, a string, the name of an input file that exists before LineStats is called 2. outFile, a string, the name of an output file that Linestats creates and writes to Important: The input file contains only upper and lower case letters and white space (no punctuation marks or other special characters). For example, if the following is the content of the file mary. txt: Mary had a Little Lamb Its fleece was white as snow And everywhere that Mary went The Lamb was sure to go The following function call: >>> inFile mary.txt >>> outFile ,marySt at s . txt >>> lineStats(inFile, outFile) should create the file maryStats.txt with the content: 12 6 14 9 17 8 11 7

Answer 1

Following is the Python3 program which counts the number of consonants and vowels from one text files and writes the stats to another text file. Screenshots of the output and the code are included at the end. Comments are placed for better understandability of the program.

Python3 CODE:

# Function to count vowels and consonants line by line

def vowel_count(line, outFile):

    # Opening the file to write stats to

    f2 = open(outFile, "a")

    vowels = set("AEIOUaeiou")

    cons = set("bcdfghjklmnpqrstvwxyzBCDFGHJKLMNPQRSTVWXYZ")

    # Counters for vowels and consonants

    countV = 0

    countC = 0

    # Loop to count vowels and consonants in each line

    for c in line:

     if c in vowels:

     countV += 1

     elif c in cons:

     countC += 1

    print("Vowels : ", countV)

    print("Consonants : ", countC)

    L =[str(countV),"\t", str(countC)+"\n"]

    # Writing the stats to the file

    f2.writelines(L)

    f2.close()

        

# Function to read lines from the inFile

def lineStats(inFile, outFile):

    f = open(inFile)

    line = f.readline()

    while line:

        print(line)

        # Call to the function to count vowels per line

        vowel_count(line, outFile)

        print("\n")

        line = f.readline()

    # Closing the file

    f.close()

# Driver code

# Opening file to read lines from

inFile = 'mary.txt'

outFile = 'maryStats.txt'

# Call to the function lineStats and pass the names of the files

lineStats(inFile, outFile)
