Write a value-returning function isvowel that returns the value true if a given character is a vowel and otherwisereturns false.

Following is the function isVowel written in python:-

def isVowel(check):#defining isVowel function with parameter check

#following are the nested if else if for checking that check is a vowel or not if yes returning True if not returning False.

   if check == "A" or check =="a":

       return True

   elif check == "E" or check =="e":

       return True

   elif check == "I" or check =="i":

       return True

   elif check == "O" or check =="o":

       return True

   elif check == "U" or check =="u":

       return True

   else:

       return False

Explanation:

In the function we are checking in each if or elif statement that check is a vowel or not if it is a vowel then returning True if not returning False.
