python使用zip时出现 zip object at 0x02A9E418

在python 3里直接print zip后的结果会出现:

例如:

 a = [1, 2, 3]
 b = (4, 5, 6)
 z = zip(a, b)
 print(z)

输出:

实际上在python3里zip后的结果是一个遍历对象

正确显示法:

a = [1, 2, 3]
b = (4, 5, 6)
z = zip(a, b)
for i in z:
    print(i)

输出:

(1, 4)
(2, 5)
(3, 6)

转为列表的形式:

a = [1, 2, 3]
b = (4, 5, 6)
z = zip(a, b)
z2 = list(z)
print(z2)

输出:

[(1, 4), (2, 5), (3, 6)]

再转为字典的形式:

a = [1, 2, 3]
b = (4, 5, 6)
z = zip(a, b)
z2 = list(z)
z3 = dict(z2)
print(z3)

输出:

{1: 4, 2: 5, 3: 6}
