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
