循环嵌套字典python中的混淆

nested dictionary python

matteo · 技术社区 · 8 年前

我正在尝试使用嵌套字典创建字典。我正在使用的所有值都来自3个不同的列表(相同长度)。

最终结果应如下所示:

d = {SP1: {TS1:[values here], TS2:[values here]}, SP2:{TS1:[other values]}}

# this should be the first key of the dictionary (SP1, SP2..), not repeated
sp = [2, 3, 4, 5, 7, 9, 9, 12, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 2, 3, 4, 5, 7, 9, 9, 12, 14, 15]

# this it the first inner key (TS1, TS2..), not repeated but coherent to the sp list values
ts = [2, 3, 3, 3, 2, 1, 3, 1, 1, 3, 2, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 2, 1, 3, 1, 1, 3]

# these values should go inside the list of each TS key
sim = [14.4953689575, 14.2694330215, 14.3503818512, 14.2953929901, 14.1140880585, 13.9398431778, 13.8227128983, 13.9122915268, 13.8505115509, 14.3296766281, 15.0080194473, 14.7962331772, 14.3174362183, 14.0135688782, 13.8948440552, 13.8888025284, 13.7929182053, 13.7562999725, 13.7984809875, 14.4026594162, 14.8861970901, 14.7377538681, 14.853559494, 14.7751989365, 14.603521347, 14.4809532166, 14.4053077698, 14.5300836563, 14.4450139999, 14.8226003647]

我试过这样的方法:

d = {}
for i, j in enumerate(sp):
    d[j] = {}
    for i in ts:
        if ts[i] not in d[j]:
            d[j] = {ts[i] : []}
            d[j][ts[i]].append(sim[i])

但是输出是错误的,因为它正在创建bot TS 键和 sim 仅取最后一个的值。

这是预期的最终词典:

d = {
2: {2: [14.4953689575, 14.8861970901]}, 
3: {3: [14.2694330215, 14.7377538681]}, 
4: {3: [14.3503818512, 14.853559494]}, 
5: {3: [14.2953929901, 14.7751989365]}, 
7: {2: [14.1140880585, 14.603521347]}, 
9: {1: [13.9398431778, 14.4809532166], 3: [13.8227128983, 14.4053077698]}, 
12: {1: [13.9122915268, 14.5300836563]}, 
14: {1: [13.8505115509, 14.4450139999]}, 
15: {3: [14.3296766281, 14.8226003647]}, 
16: {2: [15.0080194473]}, 
17: {1: [14.7962331772]}, 
18: {1: [14.3174362183]}, 
19: {1: [14.0135688782]}, 
20: {1: [13.8948440552]}, 
21: {1: [13.8888025284]}, 
22: {1: [13.7929182053]}, 
23: {2: [13.7562999725]}, 
24: {2: [13.7984809875]}, 
25: {2: [14.4026594162]}
}

inner_dicts = [{k: [v]} for k, v in zip(ts, sim)]

result = {}

for key, value in zip(sp, inner_dicts):
    result[key] = result.get(key, {})

    for inner_k, inner_v in value.items():
        result[key][inner_k] = list(set(result[key].get(inner_k, []) + inner_v))
