Question

Write a function named lineStats that finds the number of words and the number of characters on each line of a file and writes those statistics to a corresponding line of a new file, separated by a space. (Hint: when you read a line from a file, the endline character is included. Do not include the endline in the number of characters on the line.)

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.

For example, if the following is the content of the file promisedLand.txt:

The dogs on main street howl,

'cause they understand,

And I believe in a promised land I believe in a promised land...

The following function call:

inF = 'promisedLand.txt'

outF = 'promisedLandStats.txt'

lineStats(inF, outF)

should create the file promisedLandStats.txt with the content:

6 29

3 23

0 0

7 32

6 31

Answer in Python

Explanation / Answer

import sys

inF = 'promisedLand.txt'

outF = 'promisedLandStats.txt'

lineStats(inF, outF)

def lineStats(infile, outfile):

with open(infile, 'r') as inf:

for line in inf:

words = line.split()

num_words += len(words)

num_chars += len(line)-1

out = open(outfile,'a')

out.write(num_words)

out.write(" ")

out.write(num_chars)

out.write(" ")

close(out)
