Python json文件操作基因组规模模型

我的代码中有一个问题，我不知道如何修复它。基本上，我有一个json文件，看起来像这样，每个变量中只有几个数据：

{
    "metabolites": [
        {
            "id": "10fthf[c]",
            "name": "10-Formyltetrahydrofolate",
            "compartment": "c",
            "formula": "C20H21N7O7"
        },
        {
            "id": "10fthf[h]",

        },
    ],

            },
            "lower_bound": 646.06656,
            "upper_bound": 646.06656,
            "gene_reaction_rule": "",
            "subsystem": "[array(['Spectral decomposition'], dtype='<U22')]"
        },
        {

我的代码应该从表

reactions

中提取

代谢物

，其中存在列表L的ID。

嘿，您提供的json文件不是正确的json。请提供正确的文件。另外，您希望实现的具体目标是什么？请在将来使用更好的变量名，这对所有相关人员都有好处。如果您发现自己在范围（某物）中对x执行

：某物[x]

，那么您应该在某物：循环中对x使用

。if语句中的括号不是必需的<代码>L

未定义。

import json
from os.path import join
data_path= '/home/mathieu/Documents/Memoire/ESCHER_MAPPING'
with open(join(data_path,'icz843_model_PRETTY.json')) as f:
  icz843_model = json.load(f)

for x in range(len(icz843_model["metabolites"])):
    if(icz843_model["metabolites"][x]["compartment"]=="m"):
        L.append(icz843_model["metabolites"][x])
for x in range(len(icz843_model["reactions"])):
     for y in range(268):
         if(L[y]["id" in icz843_model["reactions"][x]["metabolites"]):
             print(icz843_model["reactions"][x])
