Python | Program to accept the strings which contains all vowels

Given a string, the task is check if every vowel is present or not. We consider a vowel to be present if it is present in upper case or lower case. i.e. ‘a’, ‘e’, ‘i’.’o’, ‘u’ or ‘A’, ‘E’, ‘I’, ‘O’, ‘U’ .
Examples :

Input : geeksforgeeks
Output : Not Accepted
All vowels except 'o' are not present

Input : ABeeIghiObhkUul
Output : Accepted
All vowels are present

Approach : Firstly, create set of vowels using set() function. Check for each character of the string is vowel or not, if vowel then add into the set s. After coming out of the loop, check length of the set s, if length of set s is equal to the length of the vowels set then string is accepted otherwise not.

Below is the implementation :

# Python program to accept the strings 
# which contains all the vowels 
  
# Function for check if string 
# is accepted or not 
def check(string) : 
  
    string = string.lower() 
  
    # set() function convert "aeiou" 
    # string into set of characters 
    # i.e.vowels = {'a', 'e', 'i', 'o', 'u'} 
    vowels = set("aeiou") 
  
    # set() function convert empty  
    # dictionary into empty set 
    s = set({}) 
  
    # looping through each 
    # character of the string 
    for char in string : 
  
        # Check for the character is present inside 
        # the vowels set or not. If present, then 
        # add into the set s by using add method 
        if char in vowels : 
            s.add(char) 
        else: 
            pass
              
    # check the length of set s equal to length  
    # of vowels set or not. If equal, string is   
    # accepted otherwise not 
    if len(s) == len(vowels) : 
        print("Accepted") 
    else : 
        print("Not Accepted") 
  
  
# Driver code 
if __name__ == "__main__" : 
      
    string = "SEEquoiaL"
  
    # calling function 
    check(string) 

Output:

Accepted

Alternate Implementation :

def check(string): 
    string = string.replace(' ','') 
    string = string.lower() 
    vowel = [string.count('a'), string.count('e'), string.count('i'), string.count('o'), string.count('u')] 
  
    # If 0 is present int vowel count array 
    if vowel.count(0) > 0: 
        return('not accepted') 
    else: 
        return('accepted') 
  
  
  
# Driver code 
if __name__ == "__main__" : 
      
    string = "SEEquoiaL"
  
    print(check(string)) 

Output:

accepted

Alternate Implementation 2.0 :

def check(string): 
  if len(set(string).intersection("AEIOUaeiou"))>=5: 
    return ('accepted') 
  else: 
    return ("not accepted") 
  
#Driver code 
if __name__=="__main__": 
  string="geeksforgeeks"
  print(check(string)) 

Output:

NOT Accepted
