python中reversed（）函数的用法

1 reversed(seq)
2 
3 #seq是要转换的序列，可以是str，tuple，list，range等

 1 #!/usr/bin/env python3
 2  
 3 # 字符串
 4 seqString = ‘Runoob‘
 5 print(list(reversed(seqString)))
 6  
 7 # 元组
 8 seqTuple = (‘R‘, ‘u‘, ‘n‘, ‘o‘, ‘o‘, ‘b‘)
 9 print(list(reversed(seqTuple)))
10  
11 # range
12 seqRange = range(5, 9)
13 print(list(reversed(seqRange)))
14  
15 # 列表
16 seqList = [1, 2, 4, 3, 5]
17 print(list(reversed(seqList)))

 1 #!/usr/bin/env python3
 2  
 3 # 字符串
 4 seqString = ‘Runoob‘
 5 print(list(reversed(seqString)))
 6  
 7 # 元组
 8 seqTuple = (‘R‘, ‘u‘, ‘n‘, ‘o‘, ‘o‘, ‘b‘)
 9 print(list(reversed(seqTuple)))
10  
11 # range
12 seqRange = range(5, 9)
13 print(list(reversed(seqRange)))
14  
15 # 列表
16 seqList = [1, 2, 4, 3, 5]
17 print(list(reversed(seqList)))

#以上实例的输出结果分别为：
1 [‘b‘, ‘o‘, ‘o‘, ‘n‘, ‘u‘, ‘R‘]
2 [‘b‘, ‘o‘, ‘o‘, ‘n‘, ‘u‘, ‘R‘]
3 [8, 7, 6, 5]
4 [5, 3, 4, 2, 1]
