How could I modify this code to make it valid for duplicate vowels?

Question

the_string= input("Please enter a string")
count=0

if "a" in the_string or "A" in the_string:
count+=1
if "e" in the_string or "E" in the_string:
count+=1
if "i" in the_string or "I" in the_string:
count+=1
if "o" in the_string or "O" in the_string:
count+=1
if "u" in the_string or "U" in the_string:
count+=1

if count==0:
print("Your string has zero vowels")
elif count==1:
print("Your string has one vowel")
else:
print("Your string has",count, "vowels")

Answer 1

for i in the_string:
if i in "AEIOU":
count+=1

Then your prints.

Answer 2

you also need to do:-
the_string= input("Please enter a string").upper()
# or
for i in the_string.upper()
# or
if i in "AEIOUaeiou":
