Whats the question? how come you can have multiple space chars? space char is repeated several times in the output. — Chris Doyle, Apr 20 '20 at 15:48

I am sure there will be a more elegant way to do this but for now here is a working version which you could refactor or reduce if needed

user_input = input("sentance: ")
seen = set()
filtered_words = []
for word in user_input.split():
    filtered_word = ""
    for char in word:
        if char.lower() in seen:
            continue
        filtered_word += char
        seen.add(char.lower())
    if filtered_word != "":
        filtered_words.append(filtered_word)
print(*filtered_words)
