required我有一個多級嵌套字典，只要該字典中有鍵，就會嘗試添加鍵type。
代碼：
def add_recursively(val):
if 'type' in val and val['type'] != 'object':
val['required'] = False
return val
elif 'type' in val and val['type'] == 'object' and 'object_schema' in val:
return add_recursively(val['object_schema'])
else:
val['required'] = False
return val
new_data = {}
for key, value in data.items():
if value['type'] == 'object' and 'object_schema' in value:
new_data[key] = add_recursively(value)
else:
value['required'] = False
new_data[key] = value
輸入資料：
data = {'key1': {'description': 'Configuration for OpenID', 'type': 'boolean'},
'key2': {'default': {'enabled': True, 'logging_percent': 100},
'object_schema': {'enabled': {'default': True, 'type': 'boolean'},
'logging_percent': {'default': 100, 'type': 'float'},
'nested_key': {'default': {'new_enable': True, 'new_precent': 100},
'object_schema': {'new_enable': {'default': True, 'type': 'boolean'},
'new_precent': {'default': 100, 'type': 'float'}},
'type': 'object'}},
'type': 'object'}}
輸出資料：
{'key1': {'description': 'Configuration for OpenID',
'required': False,
'type': 'boolean'},
'key2': {'enabled': {'default': True, 'type': 'boolean'},
'logging_percent': {'default': 100, 'type': 'float'},
'nested_key': {'default': {'new_enable': True, 'new_precent': 100},
'object_schema': {'new_enable': {'default': True, 'type': 'boolean'},
'new_precent': {'default': 100, 'type': 'float'}},
'type': 'object'},
'required': False}}
預期輸出：
{'key1': {
'required': False,
'description': 'Configuration for OpenID',
'type': 'boolean'},
'key2': {
'required': False,
'enabled': {'required': False, 'default': True, 'type': 'boolean'},
'logging_percent': {'required': False, 'default': 100, 'type': 'float'},
'nested_key': {'default': {'new_enable': True, 'new_precent': 100},
'object_schema': {'new_enable': {'required': False, 'default': True, 'type': 'boolean'},
'new_precent': {'required': False, 'default': 100, 'type': 'float'}},
'type': 'object'},
}}

這是通過將密鑰添加到其中包含密鑰的每個密鑰來data就地修改的一種方法：requiredtype
def add_required(d):
if 'type' in d:
d['required'] = False
for v in d.values():
if isinstance(v, dict):
add_required(v)
add_required(data)
輸出：
>>> data
{'key1': {'description': 'Configuration for OpenID',
'type': 'boolean',
'required': False},
'key2': {'default': {'enabled': True, 'logging_percent': 100},
'object_schema': {'enabled': {'default': True,
'type': 'boolean',
'required': False},
'logging_percent': {'default': 100, 'type': 'float', 'required': False},
'nested_key': {'default': {'new_enable': True, 'new_precent': 100},
'object_schema': {'new_enable': {'default': True,
'type': 'boolean',
'required': False},
'new_precent': {'default': 100, 'type': 'float', 'required': False}},
'type': 'object',
'required': False}},
'type': 'object',
'required': False}}

有多種方法可以解決這個問題（每種方法都有自己的優點和缺點），這里有一種方法可以創建（嵌套）物件的副本。
代碼00.py：
#!/usr/bin/env python

from pprint import pprint as pp

"enabled": {"default": True, "type": "boolean"},

"nested_key": {
"default": {"new_enable": True, "new_precent": 100},
"object_schema": {
"new_enable": {"default": True, "type": "boolean"},
"new_precent": {"default": 100, "type": "float"},
},
"type": "object",
}
},
"type": "object",
}
}
def add_rec(orig_data, new_items):
ret = {}
for k, v in orig_data.items():
if k == "type":
ret.update(new_items)
if isinstance(v, dict):
ret[k] = add_rec(v, new_items)
else:
ret[k] = v
return ret
def main(*argv):
new_data = add_rec(data, {"required": False})
pp(new_data)

rc = main(*sys.argv[1:])
print("\nDone.")
