return True stop the loop in Python?

Question

I am still a beginner but does not know why the \"return True\" in a \"for loop\" stop the loop after the first pass. If I use something else than \"return\", everything is fine

If you want to return True, but still keep looping, you may need a pattern like this. I'm calling the variable retval but you can call it anything that makes sense

def roc_valid(self,cote_x,cote_y):
    from graph_chess import board
    p = board()
    side=(side_x,side_y)
    retval = False

    if side == (0,0):
        for (x,y) in (0,1),(0,2),(0,3):
            print(King.ok_to_move(self,x,y))
            if p.getPiece(x,y)=="" and king.ok_to_move(self,x,y):
                retval = True

    return retval
