python中 .sort()、 sorted()和 .reverse() 、reversed()的区别

 现在举例说明：

    a = [1,4,5,3,2,4,5,6,7,8]
    b = a.sort()
    print(a)
    print(b)
    #a.sort()改变了原有序列表a
1
2
3

5

[1, 2, 3, 4, 4, 5, 5, 6, 7, 8]
None

    c = [1,4,5,3,2,4,5,6,7,8]
    d = sorted(c)
    print(c)
    print(d)
    #sorted(c)没改变原有序列表c，返回一个列表

[1, 4, 5, 3, 2, 4, 5, 6, 7, 8]
[1, 2, 3, 4, 4, 5, 5, 6, 7, 8]

    e = [1,4,5,3,2,4,5,6,7,8]
    f = e.reverse()
    print(e)
    print(f)
    #e.reverse()改变了原有序列表e

[8, 7, 6, 5, 4, 2, 3, 5, 4, 1]
None

    g = [1,4,5,3,2,4,5,6,7,8]
    h = reversed(g)
    print(g)
    print(h)
    #reversed(g)没改变了原有序列表g，返回一个迭代器
