Python Program to Count Vowels, Lines, Characters in Text File

  • Last Updated : 17 Oct, 2021

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.

  • 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:


# 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
        # 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


Number of vowels in  MyFile.txt  =  23    
New Lines in  MyFile.txt  =  2
Number of characters in  MyFile.txt  =  54
