A few Italian verbs that take a direct object, such as ascoltare, aspettare, cercare, and guardare, correspond to English verbs that are used with prepositions (to listen to, to wait for, to look for, to look at). Compare the following:

Chi cerchi? (Who are you looking for?)

Cerco il mio ragazzo. (I’m looking for my boyfriend.)

Lo cerco già da mezz’ora! (I’ve been looking for him for half an hour!)

Object pronouns are attached to ecco (here) to express the phrases "here I am," "here you are," "here he is," and so on:

Dov’è la signorina? Eccola! (Where is the young woman? Here she is!)

Hai trovato le chiavi? Sì, eccole! (Have you found the keys? Yes, here they are!)
