1.使用list的extend()方法，現有兩個list分別為L1和L2：
1 >>> L1 = [1, 2, 3, 4, 5] 2 >>> L2 = [20, 30, 40] 3 >>> L1.extend(L2) 4 >>> L1 5 [1, 2, 3, 4, 5, 20, 30, 40]
2.用切片(slice)操作，L1[len(L1):len(L1)] = L2和上面的方法等價，例如：
1 >>> L1 = [1, 2, 3, 4, 5] 2 >>> L2 = [20, 30, 40] 3 >>> L1[len(L1):len(L1)] = L2 4 >>> 5 >>> L1 6 [1, 2, 3, 4, 5, 20, 30, 40]
用切片方法的好處在於靈活，可以在任意節點進行插入，例如從頭部插入：
1 >>> L1 = [1, 2, 3, 4, 5] 2 >>> L2 = [20, 30, 40] 3 >>> L1[0:0] = L2 4 >>> L1 5 [20, 30, 40, 1, 2, 3, 4, 5]
例如加到中間：
1 >>> L1 = [1, 2, 3, 4, 5] 2 >>> L2 = [20, 30, 40] 3 >>> 4 >>> L1[1:1] = L2 5 >>> L1 6 [1, 20, 30, 40, 2, 3, 4, 5]
