Introduction
In this program we will learn how to count lines, words, characters and spaces in a given file. All these will be calculated and shown altogether.
Program
Approach 1
def read(file):
countWords, countLines, countChar, countSpace = 0,0,0,0
with open(file, 'r') as readFile:
for readLine in readFile:
countLines += 1
val = 'Y'
for readWord in readLine:
if (readWord != ' ' and val == 'Y'):
countWords += 1
val = 'N'
elif (readWord == ' '):
countSpace += 1
val = 'Y'
for readChar in readWord:
if(readChar !=" " and readChar !="\n"):
countChar += 1
print("Line count", countLines)
print("Word count: ", countWords)
print("Char count", countChar)
print("Space count", countSpace)
file = 'demo.txt'
read(file)
Output:
Approach 2
import os
def read(file):
countWords, countLines, countChar, countSpace = 0,0,0,0
with open(file, 'r') as readFile:
for readline in readFile:
readline = readline.strip(os.linesep)
list = readline.split()
countLines = countLines + 1
countWords = countWords + len(list)
countChar = countChar + sum(1 for c in readline
if c not in (os.linesep, ' '))
countSpace = countSpace + sum(1 for s in readline
if s in (os.linesep, ' '))
print("Line count", countLines)
print("Word count: ", countWords)
print("Char count", countChar)
print("Space count", countSpace)
file = 'demo.txt'
read(file)
Output:
Explanation
Approach 1:
- Open file using open() function.
- Increment line count by 1 for each loop.
- Increment word count, char count and space count depending upon the condition and return the respective values.
Approach 2:
- To separate lines we have used os.linesep() function of OS module.
- Python in-built function strip() and split() is used to extract the words, characters and counters are incremented.
