Explanation:
Direct Object pronouns can be positioned before or after main verb, depending of its form and conjugation.
On the other hand, indirect object pronoun is always located before the direct object pronoun.
e.g. Mi padre <u>me</u> compró <u>un coche</u> ayer. = Mi padre <u>me lo</u> compró ayer.
When the indirect object pronoun “le” or “les” (used for 3rd person of singular or plural) is combined with any of direct objects pronoun, <em>le</em> and <em>les</em> will change to <em>se</em>.
e.g. <u>Le</u> compré <u>un libro</u> a mi hermana. = <u>Se lo</u> compré.
