tuplea = (12,45,42,65,67,87) 
print(tuplea)
tuplea = tuplea + (9,)
print(tuplea)
tuplea = tuplea[:5] + (23,44,56) + tuplea[:5]
print(tuplea)
listx = list(tuplea)
listx.append(45)
tuplea = tuple(listx)
print(tuplea)

(12, 45, 42, 65, 67, 87)                                                                                                        

(12, 45, 42, 65, 67, 87, 9)                                                                                                     

(12, 45, 42, 65, 67, 23, 44, 56, 12, 45, 42, 65, 67)                                                                            

(12, 45, 42, 65, 67, 23, 44, 56, 12, 45, 42, 65, 67, 45)
