Hello everyone, welcome back toprogramminginpython.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.

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)
