Practice Problem 6-Vowelgram

Practice Problem 6-Vowelgram

Q.Vowelgrams are words or sentences that has every vowel (a,e,i,o,u)  of  the English alphabet occurring  at the most  once. Write an algorithm and  a subsequent Python code to check whether a string is a vowelgram or not. Write a function to check if a given string is a vowelgram. For example,”You black tiger" is a vowelgram.

Input format

First line contains the string to be checked

Output Format

Print Vowelgram or Not vowelgram

Input:

the string

Processing:

def vowelgram(string):

    count_a = string.count('a')

    count_e = string.count('e')

    count_i = string.count('i')

    count_o = string.count('o')

    count_u = string.count('u')

    if count_a in (0,1)and count_e in (0,1) and count_i in (0,1) and count_o in (0,1) and count_u in (0,1):

        return True

    else:

        return False

Output:

Display whether word is a vowelgram or not

Program:

def vowelgram(string):

    count_a = string.count('a')

    count_e = string.count('e')

    count_i = string.count('i')

    count_o = string.count('o')

    count_u = string.count('u')

    if count_a in (0,1)and count_e in (0,1) and count_i in (0,1) and count_o in (0,1) and count_u in (0,1):

        return True

    else:

        return False

string = input().rstrip()

if vowelgram(string):

    print('Vowelgram')

else:

    print('Not vowelgram')

Algorithm:

Step1. Define the function vowelgram which takes one parameter that is the string and the definition goes as follows

Step1.1. count the number of ‘a’,’e’,’i’,’o’,’u’ in the string given

Step1.2. check whether the number of vowels of each kind is one or zero if true then return True else return False

Step2. Get the string

Step3. Call the function vowelgram and let string be the parameter and check whether it return True if it does then display Vowelgram else display Not vowelgram.

Step4. End
