def Searchtype (mtype) :
            fObj = open("CINEMA.DAT", "rb")
            try:
                   while True:
                           data = pickle.load(fObj)
                           if data[2] == mtype:
                              print ("Movie number:",data[0])
                              print ("Movie Name:",data[1])
                              print ("Movie Type:",data[2])
except EOFError:
          fObj.close ()
