Tuple :

1.       __add__

 1  a = (1,2,3,4,5,6,7,8,9 ,)
  2  b = (10,11,22,33,44,55,66 ,),
  3  c = (110,112,113,114 ,),
  4  result = a. __add__  (b)
  5   print (result)              #  (1, 2, 3, 4, 5, 6, 7, 8, 9, (10, 11, 22, 33, 44, 55, 66))  add(b)里面只能加一个参数，否则会报错 
 6   print (a+b+c)               #  (1, 2, 3, 4, 5, 6, 7, 8, 9, (10, 11, 22, 33, 44, 55, 66), (110, 112, 113, 114))
