there seem to bee a problem in this python code
which i don't know were is it
simple vowel counter code

vowels = ['a','i','e','o','u']
while(True):
    print("\n\n\n\n\n\n")
    numOfVowels = 0
    Word = input("Please Enter a word to count vowles in it:")
    for letter in Word:
        if (letter in vowels):
            numOfVowels+=1;
    print("There is a " + str(numOfVowels) + " vowel letter in the word")
    choice = input("would you like a vowels summary:  (y/n)  : ")
    if(choice == 'y'):

        for i in Word:
            if (i in vowels):
                num = Word.find(i) #each letter counter
                if(num > 0):
                     print("number of " + i + " is " + str(num) ) 
#        print("number of a is " + str(Wo) )

    elif(choice == 'n'):
        print("OK \n ")

What I have tried:

vowels = ['a','i','e','o','u']
while(True):
print("\n\n\n\n\n\n")
numOfVowels = 0
Word = input("Please Enter a word to count vowles in it:")
for letter in Word:
if (letter in vowels):
numOfVowels+=1;
print("There is a " + str(numOfVowels) + " vowel letter in the word")
choice = input("would you like a vowels summary: (y/n) : ")
if(choice == 'y'):

for i in Word:
if (i in vowels):
num = Word.find(i) #each letter counter
if(num > 0):
print("number of " + i + " is " + str(num) )
# print("number of a is " + str(Wo) )

elif(choice == 'n'):
print("OK \n ")
