Considering only the alphabetical characters, consonants having the value oftheir ASCII codes, and vowels having the inverse value of their ASCII codes,what is the sum of the sentence code example

Example: output percentage of vowels and consonants in a given file in python

# 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)
