Question

3. Write a Python module, mymod.py, that counts the lines and characters in a file.

It should contain the following functions:

• A countLines(name)function that reads an input file and returns a count

ofthe number of lines in it.

• A countChars(name)function that reads an input file and returns a count

ofthe number of characters in it.

• A countWords(name)function that reads an input file and returns a count

of the number of words in it.

• An avgWordLength(name)function that reads an input file and returns

the average word length about all of the words in the file.

You must also include a test script, test.pythat imports the module and calls each

of these functions and prints their output. Similarly, you must also supply the text

file that you used to test your functions.

Explanation / Answer

def countLine(name):
count = 0
f=open(name)

for line in f:
count=count +1

f.close()
return count

def countChars(name):
count = 0
f=open(name)

for line in f:
for c in line:
count=count +1

f.close()
return count

def countWords(name):
count = 0
f=open(name)

for line in f:
line=line.split()
for i in line:
count=count +1

f.close()
return count

def avgWordLength(name):
return countChars(name)/countWords(name)
