I have been stuck on a problem for 2 days. This is using vocareum software for python where we all have different questions. I was able to get it to pass tests 1-4 before it stops at test 5. I can see why it is not passing as I need to uppercase the letter "i" in certain areas. I am just unsure how to code this to make it work without altering the previous ones.

quote = input("Please enter a paragraph: ")

print(quote)

quote = quote.lower()

word = input("Please enter a common word: ")

print(word)

word = word.lower()

where = quote.find(word)

failsafe = 30

while where >= 0:

print("Found " + word + " at position "+ str(where))

left = quote[:where]

right = quote[where+len(word):]

quote = left + word.upper() + right

print(quote)

where = quote.find(word)

failsafe = failsafe - 1

if failsafe <= 0:

break
