Answer 1

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])
