there are lessons you can learn from twilight (the thing u can learn from harry potter is how to do a spell on your friend so he can help u)

No just no. There are innumerable lessons you can learn from the Harry Potter books, if you care enough to read them! *note how they conveniently didn't include any of these so-called lessons from twilight...*
I learned lessons in true friendship. Harry, Ron and Hermione are inseparable and true friends and stick by each other through thick and thin. Their bonds of friendship save each other countless times.
I learned the power of love. Similar to friendship, love was one of the vital themes in the books. Lily Potter saved her son because she sacrificed herself for him, and love was the one thing Voldemort could not understand. As Dumbledore says, "do not pity the dead, Pity the living, and above all pity those who live without love" (sry if that quote's not completely accurate, doing it from memory rn)
I learned to be proud of who I am. So maybe all our characters aren't super models, but that is equally important if not more than having a pretty face. Hermione was often described as borderline ugly or unattractive, but she showed that intellect can be far more valuable than outer beauty. Luna was dorky in the extreme but she loved herself, and her friends loved her for it. They showed girls worldwide that they don't have to be 'beautiful' to be a beautiful person.
These are only three lessons one can take away from the Harry Potter series, and there are many more. So no, the only thing you can learn from Harry Potter is NOT "how to do a spell on your friend so he can help u"
