Hello everyone, welcome back to programminginpython.com! Here in this tutorial am going to tell how you can count vowels in a string when an input string is received you will be able to count the number of vowels present in that string.
Master the basics of data analysis in Python. Expand your skillset by learning scientific computing with numpy.
Take the course on Introduction to Python on DataCamp here https://bit.ly/datacamp-intro-to-python

Task
Python program to count the number of each vowel in a given string.
Approach
- Read an input string using
input()orraw_input(). - Declare vowels as a string `vowels = ‘aeiou’`
- Make the input string case insensitive using `casefold()` method
- Create a dictionary with each vowel a key and value 0
- Loop the string and check for vowels and if found increment the value in the dictionary
- Print the result(dictionary)
Program
__author__ = 'Avinash'
# Python3 program to count vowels in a string
# string of vowels
vowels = 'aeiou'
input_str = input("Enter a string: ")
# make input string case insensitive
input_str = input_str.casefold()
# make a dictionary with each vowel a key and value 0
vowels_count = {}.fromkeys(vowels, 0)
# count the number of each vowels
for letter in input_str:
if letter in vowels_count:
vowels_count[letter] += 1
print(vowels_count)
Output
Count Vowels in a String – Code Visualization
