Python对于json数据键值对遍历

{
    "name": "Alice",
    "age": 25,
    "skills": ["Python", "Java", "c++"],
    "address": {
        "city": "Beijing",
        "country": "China"
    }
}

import json

data = '{"name": "Alice", "age": 25, "skills": ["Python", "Java", "C++"], "address": {"city": "Beijing", "country": "China"}}'
result = json.loads(data)

for key, value in result.items():
    print(key, value)

print(result['address']['city'])  # 输出'Beijing'

for skill in result['skills']:
    print(skill)

age = {
    'Tom': 18,
    'Jerry': 12,
    'Bob': 23,
    'Ann': 31
}
for key, value in age.items():
    print(f"Key:{key},Value:{value}")
 
# output:
# Key:Tom,Value:18
# Key:Jerry,Value:12
# Key:Bob,Value:23
# Key:Ann,Value:31
