Accepting Strings Containing All Vowels Program

This program is designed to accept a string that contains all vowels (a, e, i, o, u). The program will check if the string contains all vowels and return a message accordingly.

Algorithm
  1. Create a set of vowels containing all vowels (a, e, i, o, u)
  2. Ask the user to input a string
  3. Convert the string to lowercase
  4. Iterate through each character in the string
  5. If the character is a vowel, remove it from the set of vowels
  6. If the set of vowels is empty, the string contains all vowels, else, it does not.
  7. Output a message to the user indicating whether the string contains all vowels or not.
Code Implementation
vowels = set('aeiou')

def contains_all_vowels(s):
    s = s.lower()
    for character in s:
        if character in vowels:
            vowels.remove(character)
        if not vowels:
            return True
    return False

s = input("Enter a string: ")
if contains_all_vowels(s):
    print("The string contains all vowels!")
else:
    print("The string does not contain all vowels.")

The code above defines a function contains_all_vowels that accepts a string s as an argument. The function iterates through each character in the string and removes it from the set of vowels if it is a vowel. If the set of vowels is empty after iterating through the string, the function returns True, otherwise it returns False.

The code prompts the user to enter a string and checks if it contains all vowels using the contains_all_vowels function. It then outputs a message to the user indicating whether the string contains all vowels or not.

Conclusion

In conclusion, this program can be useful for verifying whether a string contains all vowels or not. It uses a simple algorithm to check for the presence of each vowel in the string and returns a message accordingly.
