In this article, we are going to create a python program that counts vowels, lines, and a number of characters present in a particular text file.
Approach
- We have to open the file using open() function in python.
- Then make three variables, vowel, line and character to count the number of vowels, lines, and characters respectively.
- Make a list of vowels so that we can check whether the character is a vowel or not.
- When the count hits the ‘\n’ character we have to increase our line variable means a new line in the file.
- After that iterate over the characters of the file and count the vowels, lines, and characters.
Below is the full Implementation:
Python3
# Python program to count number of vowels, # newlines and character in textfile def counting(filename):
# Opening the file in read mode
txt_file = open (filename, "r" )
# Initialize three variables to count number of vowels,
# lines and characters respectively
vowel = 0
line = 0
character = 0
# Make a vowels list so that we can
# check whether the character is vowel or not
vowels_list = [ 'a' , 'e' , 'i' , 'o' , 'u' ,
'A' , 'E' , 'I' , 'O' , 'U' ]
# Iterate over the characters present in file
for alpha in txt_file.read():
# Checking if the current character is vowel or not
if alpha in vowels_list:
vowel + = 1
# Checking if the current character is
# not vowel or new line character
elif alpha not in vowels_list and alpha ! = "\n" :
character + = 1
# Checking if the current character
# is new line character or not
elif alpha = = "\n" :
line + = 1
# Print the desired output on the console.
print ( "Number of vowels in " , filename, " = " , vowel)
print ( "New Lines in " , filename, " = " , line)
print ( "Number of characters in " , filename, " = " , character)
# Calling the function counting which gives the desired output counting( 'Myfile.txt' )
|
Output:
Number of vowels in MyFile.txt = 23 New Lines in MyFile.txt = 2 Number of characters in MyFile.txt = 54
