Write a python program that gets a single character from the user and writes out a congratulatory message if the character is a vowel (a, e, i, o, or u), but otherwise writes out a "you lose, better luck next time" message.

def vowel(a):  #function to detect whether the character is vowel or not.

   vow=['a','e','i','o','u'] #list of vowels.

   if a in vow:

       return True

   else:

       return False

character=str(input("Enter the character \n")) #taking input.

if vowel(character.lower()):#checking the character is vowel using the function vowel..

   print("Congratulations") #congratulating.

else:

   print("You lose better luck next time")#message.

Output:-

Enter the character  

a
