Python Program to Count the Number of Each Vowel

 # Program to count the number of each vowels

# string of vowels

vowels = 'aeiou'

ip_str = 'Hello, have you tried our tutorial section yet?'

# 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)

Source Code: Using a list and a dictionary comprehension

# Using dictionary and list comprehension

ip_str = 'Hello, have you tried our tutorial section yet?'

# make it suitable for caseless comparisions

ip_str = ip_str.casefold()

# count the vowels

count = {x:sum([1 for char in ip_str if char == x]) for x in 'aeiou'}

print(count)

Output

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