Q. Write a program with a user-defined function with string as a parameter which replaces all vowels in the string with "*".

Answer =

def replaceVowels (st) :
    newstr = ''
    for character in st:
        if character in 'aeiouAEIOU':
            newstr += '*'
            
        else:
            newstr += character
    return newstr

st = input ("Enter a String: ")
st1 = replaceVowels (st)
print ("The original String is:", st)
print ("The modified String is:", st1)

Output :-

Enter a String: Computer Portal
The original String is:-  Computer Portal
The modified String is:-  C*mp*t*r P*rt*l
>>>

Enter a String: PathWalla
The original String is:-  PathWalla
The modified String is:-  P*thW*ll*
