tuple and list 练习

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))

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)  有没有逗号的区别哈哈
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)
