Answer 1

Try this!

title_words = []
for item in set(text6):
    if item.istitle():
        title_words.append(item)
print(len(title_words))

Or more pythonic:

title_words = [x for x in set(text6) if x.istitle()]
print(len(title_words))

Answer 2

def check(word): if(word[0].isupper()==True and word[1:len(word)].islower()==True): return word else: return False print(check("App"))

Answer 3

for update we can use input but in online compiler it throws eof erorr

def check(word): if(word[0].isupper()==True and word[1:len(word)].islower()==True): return word else: return False text6=set() text6.update(["word","App","Jsk"]) for i in text6:

print(check(i))
