Number of each vowel in a string

Aim: Implement a Program to count the number of each vowel in a string

Algorithm:

1.Start

2.Enter the string s.

3.Take each character in the string and compare with ‘a,e,i,o,u’.

4.If found increment corresponding counter by one.

5.Print the counter values.

6.Stop

Program:

# string of vowels

vowels = 'aeiou'

# take input from the user

ip_str = input("Enter a string: ")

# make it suitable for caseless comparisions

ip_str = ip_str.casefold()

# make a dictionary with each vowel a key and value 0

count = {}.fromkeys(vowels,0)

# count the vowels

for char in ip_str:

   if char in count:

       count[char] += 1

print(count)

Output:

Enter a string: Hello, have you tried our turorial section yet?

{'e': 5, 'u': 3, 'o': 5, 'a': 2, 'i': 3}4)
