python 嵌套字典比较值，取值

Posted 2020-09-24

#取值
import types
allGuests = {‘Alice‘: {‘apples‘: 5, ‘pretzels‘: {‘12‘:{‘beijing‘:456}}},
             ‘Bob‘: {‘ham sandwiches‘: 3, ‘apple‘: 2},
             ‘Carol‘: {‘cups‘: 3, ‘apple pies‘: 1}}
def dictget(dict1,obj,default=None):
	for k,v in dict1.items():
		if k == obj:
			print(v)
		else:
			if type(v) is dict:
				re=dictget(v,obj)
				if re is not default:
					print(re)
dictget(allGuests,‘beijing‘)

　　结果：

比较大小

 

def bijiaodict(dict1,dict2):
    for k,v in dict1.items():
        for k2,v2 in dict2.items():
            if k==k2 and v==v2:
                print(‘dict1=dict2‘)
            else:
                print(‘dict1!=dict2‘)
dict1={‘2‘:‘6‘}
dict2={2:{1:{1:8}}}
bijiaodict(dict1,dict2)

结果：
