初级列表推导式：[expression for target in Object]
list=[i for i in range(10)] print(list)高级列表推导式：(1):[expression target in Object if condition] (2)[expression for target1 in Object1 for target2 in Object …]
"""第一种""" list=[i for i in range(11) if i%2==0] print(list) """第二种""" list=[[i,j] for i in range(3) for j in range(3)] print(list)超级列表推导式：[expression for target1 in Object if condition1 for target2 in Object if condition2 …]
list=[[i,j,k] for i in range(3) if i%2==0 for j in range(3) if i%2==0 for k in range(3) if i%2==0] print(list)上面的表达式可以灵活运用，这里只是一些简单的例子。
运行结果：
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9] [0, 2, 4, 6, 8, 10] [[0, 0], [0, 1], [0, 2], [1, 0], [1, 1], [1, 2], [2, 0], [2, 1], [2, 2]] [[0, 0, 0], [0, 0, 1], [0, 0, 2], [0, 1, 0], [0, 1, 1], [0, 1, 2], [0, 2, 0], [0, 2, 1], [0, 2, 2], [2, 0, 0], [2, 0, 1], [2, 0, 2], [2, 1, 0], [2, 1, 1], [2, 1, 2], [2, 2, 0], [2, 2, 1], [2, 2, 2]]
