Here we list attractions and sights in Prague. List surly isn’t complete and it is not possible to see everything, even if you stay one week. Attractions which you have to visit are: Charles Bridge, Old Town Square including Astronomical Tower, Prague Castle and possibly Jewish Quarter. If won’t visit them honestly you cannot say you have been in Prague :) All other sights consider visiting based on your personal preference and time ... It is also quite good idea to take some guided tour.
