所以我在這里有一個大的 JSON 檔案，它看起來像這樣：
data = {
"Module1": {
"Description": "",
"Layer": "1",
"SourceDir": "pathModule1",
"Attributes": {
"some",
},
"Vendor": "comp",
"components":{
"Component1": {
"path": "something",
"includes": [
"include1",
"include2",
"include3",
"include4",
"include5"
]
"generated:" "txt"
"memory:" "txt"
etc
},
"Component2":{
"path": "something",
"includes": [
"include1",
"include2",
"include3",
"include4",
"include5"
]
"generated:" "txt"
"memory:" "txt"
etc
}
}
},
"Module2": {
"Description": "",
"Layer": "2",
"SourceDir": "pathModule2",
"Attributes": {
"some",
},
"Vendor": "comp",
"components":{
"Component1": {
"path": "something",
"includes": [
"include1",
"include2",
"include3",
"include4",
"include5"
]
"generated:" "txt"
"memory:" "txt"
etc
},
"Component2":{
"path": "something",
"includes": [
"include1",
"include2",
"include3",
"include4",
"include5"
]
"generated:" "txt"
"memory:" "txt"
etc
}
}
},
"Module3": {
"Description": "",
"Layer": "3",
"SourceDir": "path",
"Attributes": {
"some",
},
"Vendor": "",
},
"Module4": {
"Description": "",
"Layer": "4",
"SourceDir": "path",
"Attributes": {
"some",
}
}
}
我必須經歷并從中取出一些東西，所以最后我得到了這個：
每當供應商欄位等于“comp”時，請考慮該模塊，考慮它的 SourceDir 欄位、所有組件、它們的路徑和包含。
所以輸出將是：
Module1, "pathModule1", components: [Component1, path, [includes: include1, include2 ,include3 ,include4 ,include5 ]], [Component2, path, includes: [include1, include2 ,include3 ,include4 ,include5 ]]
Module2, "pathModule2", components: [Component1, path, [includes: include1, include2 ,include3 ,include4 ,include5 ]], [Component2, path, includes: [include1, include2 ,include3 ,include4 ,include5 ]]
我真的很難訪問我需要的所有欄位。
我目前的代碼是這樣的：
with open ("DB.json", 'r') as f:
modules= json.load(f)
for k in modules.keys():
try:
if swc_list[k]["Vendor"] == "comp":
list_components.append(k)
sourceDirList.append(swc_list[k]['SourceDir'])
for i in swc_list[k]['sw_objects']:
list_sw_objects.append((swc_list[k]['sw_objects']))
except KeyError:
continue
我設法只獲得 Module1 和 sourceDir，而不是 Component1、2 及其屬性.. 我怎樣才能做到這一點？
謝謝！
uj5u.com熱心網友回復：
我將首先過濾掉您不感興趣的專案，方法是：
data = {k: v for k,v in data.items() if v.get("Vendor") == "comp"}
這會洗掉您不想要的所有模塊。這有點低效，因為您要再次決議字典以獲取所需格式的資料，但作為第一步更容易推理，這很有幫助！
此時，如果需要，您可以再次遍歷字典 - 您會得到如下內容：
{'Module1': {'Attributes': {'some'},
'Description': '',
'Layer': '1',
'SourceDir': 'pathModule1',
'Vendor': 'comp',
'components': {'Component1': {'includes': ['include1',
'include2',
'include3',
'include4',
'include5'],
'path': 'something'},
'Component2': {'includes': ['include1',
'include2',
'include3',
'include4',
'include5'],
'path': 'something'}}},
'Module2': {'Attributes': {'some'},
'Description': '',
'Layer': '2',
'SourceDir': 'pathModule2',
'Vendor': 'comp',
'components': {'Component1': {'includes': ['include1',
'include2',
'include3',
'include4',
'include5'],
'path': 'something'},
'Component2': {'includes': ['include1',
'include2',
'include3',
'include4',
'include5'],
'path': 'something'}}}}
要僅列印源目錄和組件，您可以執行以下操作：
for k,v in data2.items():
print(k, v["SourceDir"], v["components"])
這會給你：
Module1 pathModule1 {'Component1': {'path': 'something', 'includes': ['include1', 'include2', 'include3', 'include4', 'include5']}, 'Component2': {'path': 'something', 'includes': ['include1', 'include2', 'include3', 'include4', 'include5']}}
Module2 pathModule2 {'Component1': {'path': 'something', 'includes': ['include1', 'include2', 'include3', 'include4', 'include5']}, 'Component2': {'path': 'something', 'includes': ['include1', 'include2', 'include3', 'include4', 'include5']}}
編輯： 要進一步細化輸出，您可以將上述回圈更改為：
for k,v in data2.items():
components = [(comp_name, comp_data["path"], comp_data["includes"]) for comp_name, comp_data in v["components"].items()]
print(k, v["SourceDir"], components)
這會給你：
Module1 pathModule1 [('Component1', 'something', ['include1', 'include2', 'include3', 'include4', 'include5']), ('Component2', 'something', ['include1', 'include2', 'include3', 'include4', 'include5'])]
Module2 pathModule2 [('Component1', 'something', ['include1', 'include2', 'include3', 'include4', 'include5']), ('Component2', 'something', ['include1', 'include2', 'include3', 'include4', 'include5'])]
