python 多层list 转dict问题

Question

我有一个list如下

list=[[['upstream', 'aa'], [['server', '172.16.1.6']]], [['upstream', 'bb'], [['server', '172.16.1.6:8080']]], [['server'], [['listen', '80'], ['server_name', 'aaa.test.com']]]]

类似上面的，可能还有更多层嵌套

请问这样的list,我怎么转换成dict

最好是类似

{'upstream:aa','server:172.16.1.6'}

这种

请注意，list里[]是分块的，这个分块对解析有意义，所以不能完全使用flatten()之类的压平。否则解析的时候就乱了。

目前 松林给出的代码，运算出来的答案是我想要的，不过实际上我的列表嵌套层数还更多一些。

不知道怎么解决。。

更新问题

首先感谢各位的答案

其次，楼下第一的答案
如果这个list里有key是一样的，但是value可能有两个以上，比如

[[['location', '/']
.........
[['location', '~', '.*\.(ico|gif|jpg|jpeg|png|bmp|swf)$']]]]

在一个大的[]里，出现两次location,并且第二次的location有2个以上的value

[['location', '/']被后面的覆盖，而后面的因为有2个value，导致不满足key, value = lst if len(lst)==2 else (lst[0], '')，于是匹配不到[['location', '/']

Answer 1

I wrote one, just to test the example you gave me, and see if it’s what you want:

lst=[
        [
            ['upstream', 'aa'], 
            [
                ['server', '172.16.1.6']
            ]
        ],
        [
            ['upstream', 'bb'],
            [
                ['server', '172.16.1.6:8080']
            ]
        ],
        [
            ['server'], 
            [
                ['listen', '80'],
                ['server_name', 'aaa.test.com']
            ]
        ]
    ]

def turn2dic(lst):
    dic = {}
    if all([not isinstance(item, list) for item in lst]):
        key, value = lst if len(lst)==2 else (lst[0], '')
        dic[key] = value
    else:
        for item in lst:
            subdic = turn2dic(item)
            dic.update(subdic)
    return dic

results = []

for item in lst:
    results.append(turn2dic(item))

print results

Answer 2

You can do this

ret = []
for i in lst:
    d = {}
    d[i[0][0]] = i[0][1] if len(i[0])>1 else ''
    d.update({k:v for k, v in i[1]})
    ret.append(d)
print ret

Results

[{'server': '172.16.1.6', 'upstream': 'aa'},
 {'server': '172.16.1.6:8080', 'upstream': 'bb'},
 {'listen': '80', 'server': '', 'server_name': 'aaa.test.com'}]

Answer 3

Under what circumstances would such an inhumane list be designed?

Answer 4

Is there an idea like this? First convert the list into a string
Then run a while loop and use the replace function to replace the square brackets
For example, '[[[' is replaced with '3', ']]' is replaced with ' -2'
Then cumsum the replaced number
Once you get 1, cut it and you can get the result
Try it, if it doesn't work, come up with the code
