二维数组在python中给出不正确的结果

Question

我有这个代码通过循环

创建2d数组

result = dict()
final = dict()

with open(self.json_file , 'w') as outfile:
    for entry in sections_list:
        path_items = raw_config.items(entry)
        for key,path in path_items:
            final[key]=path
            result[entry] = final
    json.dump(result, outfile)

但结果我得到了每个条目的所有关键，路径！ 该怎么办 ？？？

从你的代码中，我认为你想要一个包含dict元素的dict，你可以这样做：

result = dict()
with open(self.json_file , 'w') as outfile:
    for entry in sections_list:
        path_items = raw_config.items(entry)
        result[entry] = dict()
        for key,path in path_items:
            result[entry][key] = path

    json.dump(result, outfile)

如果path_items是包含两个元素的list / tuple的列表/元组，则可以使代码更简单：

result = dict()
with open(self.json_file , 'w') as outfile:
    for entry in sections_list:
        path_items = raw_config.items(entry)
        result[entry] = dict(path_items)

    json.dump(result, outfile)
