我试图遍历一个大字典来找到某些键，我尝试使用一些代码来遍历在另一个问题上找到的字典，但是我得到了一个错误：
Traceback (most recent call last):
File "C:\Users\ellioclv\Desktop\Test\pthonProcess.py", line 86, in <module>
processModelFolder(modelFolder)
File "C:\Users\ellioclv\Desktop\Test\pthonProcess.py", line 63, in processModelFolder
dictWalk(python_obj, IDCO)
File "C:\Users\ellioclv\Desktop\Test\pthonProcess.py", line 75, in dictWalk
stack = d.id()
AttributeError: 'str' object has no attribute 'id'
我认为这与包含列表而不是其他字典的字典有关，有没有办法使这项工作有效，或者将所有内容转换为字典？
这是有问题的代码段：
else:
with open(fileName , "r") as in_file:
IDCO = None
for n, line in enumerate(in_file, 1):
if line.startswith('IDCO_IDENTIFICATION'):
#Checks if the second part of each line is a ID tag in IDs
if line.split('"')[1] in IDs:
#If ID found it is stored as IDCO
IDCO = line.split('"')[1]
else:
if IDCO:
pass
IDCO = None
#Checks if the first part of each line is a Prop in Propterties
elif IDCO and line.split(' ')[0] in Properties:
print('Found! ID:{} Prop:{} Value: {}'.format(IDCO, line.split('=')[0][:-1], line.split('=')[1][:-1]))
print("\n")
#Stores the property name and value
name = str(line.split(' ')[0])
value = str(line.split(' ')[2])
#json file editing
with open(fileNameThree , "r+") as json_data:
python_obj = json.load(json_data)
dictWalk(python_obj, IDCO)
with open(fileNameThree , "w") as json_data:
json.dump(python_obj, json_data, indent = 1)
print('Processed {} lines in file {}'.format(n , fileName))
def dictWalk(obj, key):
stack = d.id()
while stack:
k, v = stack.pop()
if isinstance(v, dict):
stack.extend(v.iteritems())
else:
print("Made it")
这是上下文的所有代码：

from collections import OrderedDict
#Finds and lists the folders that have been provided
d='.'
folders = list(filter (lambda x: os.path.isdir(os.path.join(d, x)), os.listdir(d)))

fileNameThree = os.path.join(d, inFolder, inFolder + "APPENDED.vg2.json")
#copying the json file so the new copy can be appended
shutil.copyfile(fileNameTwo, fileNameThree)
#assigning IDs and properties to search for in the mdl file

Properties = ["IDSU_FX[0]","IDSU_FY[0]","IDSU_FZ[0]"]
#Basic check to see if IDs and Properties are valid

print(i)
print("\n")

print("No IDs were given!")
elif len(Properties) == 0:
print("No Properties were given!")
#Reads code untill an ID is found
else:

为了清楚起见，这是一些加载到dict python_obj中的json文件（该文件的长度超过79000行，因此请忽略它遗漏了大量的右括号，我只用了前300行为了显示它的外观，整个json文件的结构类似于所示示例）：
