[英]how to get all keys&values in nested dict of list-of-dicts and dicts?
{'action_name':'mobile signup',
'functions':[{'name':'test_signUp',
'parameters':{'username':'max@getappcard.com',
'password':'12345',
'mobileLater':'123454231',
'mobile':'1e2w1e2w',
'card':'1232313',
'cardLater':'1234321234321'}}],
'validations':[
{'MOB_header':'My stores'},
{'url':"/stores/my"}]}
I want to get all the keys & values of this dict as a list (out of values that they are dict or array)我想将这个 dict 的所有键和值作为列表(从它们是 dict 或数组的值中获取)
print result should be like this:打印结果应该是这样的:
action name = mobile signup
name = test_signUp
username : max@getappcard.com
password : 12345
mobileLater: 123454231
mobile : 1e2w1e2w
card : 1232313
cardLater : 1234321234321
MOB_header : My stores
You might want to use a recursive function to extract all the key, value
pairs.您可能希望使用递归函数来提取所有key, value
对。
def extract(dict_in, dict_out):
for key, value in dict_in.iteritems():
if isinstance(value, dict): # If value itself is dictionary
extract(value, dict_out)
elif isinstance(value, unicode):
# Write to dict_out
dict_out[key] = value
return dict_out
Something of this sort.这种东西。 I come from C++ background so I had to google for all the syntaxes.我来自 C++ 背景,所以我不得不谷歌搜索所有语法。
a little late but for python 3.8 you can use yield from
有点晚了,但对于 python 3.8,你可以使用yield from
def dictitems2list(d):
for k, v in d.items():
yield k
if isinstance(v, dict):
yield from get_all_items(v)
else:
yield v
all_itemt = list(dict2items(d))
I have modified a little bit from this link to get all keys&values in nested dict of list-of-dicts and dicts:我已经从这个链接中修改了一点,以获取字典列表和字典的嵌套字典中的所有键和值:
def recursive_items(dictionary):
for key, value in dictionary.items():
if type(value) is dict:
yield (key, value)
yield from recursive_items(value)
elif type(value) is list:
yield (key, value)
for i in value:
if type(i) is dict:
yield from recursive_items(i)
else:
yield (key, value)
for i in recursive_items(your_dict):
print(i) #print out tuple of (key, value)
Output:输出:
('action_name', 'mobile signup')
('functions', [{'name': 'test_signUp', 'parameters': {'username':
'max@getappcard.com', 'password': '12345', 'mobileLater': '123454231', 'mobile':
'1e2w1e2w', 'card': '1232313', 'cardLater': '1234321234321'}}])
('name', 'test_signUp')
('parameters', {'username': 'max@getappcard.com', 'password': '12345',
'mobileLater': '123454231', 'mobile': '1e2w1e2w', 'card': '1232313',
'cardLater': '1234321234321'})
('username', 'max@getappcard.com')
('password', '12345')
('mobileLater', '123454231')
('mobile', '1e2w1e2w')
('card', '1232313')
('cardLater', '1234321234321')
('validations', [{'MOB_header': 'My stores'}, {'url': '/stores/my'}])
('MOB_header', 'My stores')
('url', '/stores/my')
