将列表的字典转换为字典的字典

Question

当前输出为格式，列表字典

{
"majestic-service-1.324.02070909": [
"/home/robotics/arm-services/FeaturesDir.yaml",
"/home/robotics/arm-service/majestic-service.tar.gz"
],
}

，我希望将输出格式更改为如下所示。(字典的字典)

{
"majestic-service-1.324.02070909": {
"yaml_file": "/home/robotics/arm-services/FeaturesDir.yaml",
"tar_file": "/home/robotics/arm-services/majestic-service-1.324.02070909.tar.gz",
"kind": "FeaturesDir"
}
}

我尝试过的相应代码片段，

output_dict = {}
for file in application_files:
match = re.match(regex_pattern, os.path.basename(file))
if match:
if os.path.exists(os.path.join(os.path.dirname(file), "FeaturesDir.yaml")):
output_dict[file_without_extension(match.string)] = {os.path.join(os.path.dirname(file), "FeaturesDir.yaml")}
output_dict[file_without_extension(match.string)].append(file)
output_dict["Kind"] = "FeaturesDir"
elif os.path.exists(os.path.join(os.path.dirname(file), "output_path/Deviations.yaml")):
output_dict[file_without_extension(match.string)] = {os.path.join(os.path.dirname(file), "output_path/Deviations")}
output_dict[file_without_extension(match.string)].append(file)
output_dict["Kind"] = "Deviations"
# where the function file_without_extension, will return - majestic-service-1.324.02070909 from majestic-service-1.324.02070909.tar.gz

报告以下错误

AttributeError: 'set' object has no attribute 'append'

我做错了什么?

出现错误是因为在这一行output_dict[file_without_extension(match.string)] = {os.path.join(os.path.dirname(file), "output_path/Deviations")}中，您使用了{}括号，对于python来说，这是作为称为set的数据类型。集合没有追加属性，只有添加属性但这是完全不同的数据类型。这就是为什么它会显示出这种错误!
