In this Python program, we will learn how to count the number of each vowel in a given string entered by the user.

Here is the Source code of the program to count the number of each vowel in a string entered by the user.

# Python Program to Count the Number of Each Vowel in a String Entered By the User

# string of vowels
vowels = 'aeiou'

# To Take the Input From User
mystr=input("Enter the String: ")

# make it suitable for caseless comparisions
mystr = mystr.casefold()

# make a dictionary with each vowel a key and value 0
count = {}.fromkeys(vowels,0)

# count the vowels
for char in mystr:
   if char in count:
       count[char] += 1

print(count)

In this above program, we used the casefold() function which returns the string in the lowercase string and fromkeys() function to create a new dictionary withs its key and value.
