在python中使用for循环生成动态嵌套JSON
我是Python的新手。我在python中使用for循环生成嵌套JSON时遇到一些困难。为了生成嵌套的JSON,我在运行时得到了字典的长度,并根据字典的长度生成了嵌套的JSON。我得到的词典长度是4。词典的长度可能会有所不同。这是我的数据字典:在python中使用for循环生成动态嵌套JSON,python,json,dictionary,dynamically-generated,Python,Json,Dictionary,Dynamically Generated,我是Python的新手。我在python中使用for循环生成嵌套JSON时遇到一些困难。为了生成嵌套的JSON,我在运行时得到了字典的长度,并根据字典的长度生成了嵌套的JSON。我得到的词典长度是4。词典的长度可能会有所不同。这是我的数据字典: data_dict = {"PHOTO_1" : {"key1" : "PHOTO_2", "key2" : "PHOTO_3", "key3" : "PHOTO_4"}, "PHOTO_2" : {"key1" : "PHOTO_1", "key2"

请帮忙。我不知道如何解决这个问题?请不要把它标为重复的。我已经检查了所有答案,我的JSON查询完全不同。使用函数的解决方案:
import itertools, json
data_dict = {"first_photo" : "PHOTO_1", "second_photo" : "PHOTO_2", "Thrid" : "PHOTO_3"}
result = {"Requests":[]}
for pair in sorted(itertools.permutations(data_dict.values(), 2)):
result["Requests"].append({"photo":{"photoId":{"id": pair[0]},
"connections":{"target":{"id": pair[1]}}},"updateData": "connections"})
print(json.dumps(result, indent=4))
新输入指令的附加方法:
data_dict = {"PHOTO_1" : {"key1" : "PHOTO_2", "key2" : "PHOTO_3", "key3" : "PHOTO_4"}, "PHOTO_2" : {"key1" : "PHOTO_1", "key2" : "PHOTO_3"},"PHOTO_3" : {"key1" : "PHOTO_2"},"PHOTO_4" : {"key1" : "PHOTO_1", "key2" : "PHOTO_2", "key3" : "PHOTO_3"}}
result = {"Requests":[]}
for k,d in sorted(data_dict.items()):
for v in sorted(d.values()):
result["Requests"].append({"photo":{"photoId":{"id": k},
"connections":{"target":{"id": v}}},"updateData": "connections"})
print(json.dumps(result, indent=4))
的可能重复项是否词典始终长度
3
?@RomanPerekhrest否,词典长度未固定。它是不同的。您的json无效,您不能有相同的目标
keys@ArunaRajput,你有我的解决办法吗
