# Python Program to Count Vowels and Consonants in a String

str1 = input("Please Enter Your Own String : ")
vowels = 0
consonants = 0

for i in str1:
    if(i == 'a' or i == 'e' or i == 'i' or i == 'o' or i == 'u'
       or i == 'A' or i == 'E' or i == 'I' or i == 'O' or i == 'U'):
        vowels = vowels + 1
    else:
        consonants = consonants + 1
 
print("Total Number of Vowels in this String = ", vowels)
print("Total Number of Consonants in this String = ", consonants)

Example 2: count vowels

vow = ['a', 'A', 'e',
          'E', 'i', 'I',
          'o', 'O', 'U',
          'u', 'Y', 'y']

def vowels(str):
  
  global vow
  string = list(str)
  count = 0
  
  for i in range(len(string)):
    
    if string[i] in vow:
      
      count += 1
  return count
