如何使用python解析键值数据

data = {
    "key1": "value1",
    "key2": "value2",
    "key3": "value3"
}

# 访问特定键的值
print(data["key1"])  # 输出：value1

# 遍历所有键值对
for key, value in data.items():
    print(key, value)

import json

json_data = '{"key1": "value1", "key2": "value2", "key3": "value3"}'
data = json.loads(json_data)

# 访问特定键的值
print(data["key1"])  # 输出：value1

# 遍历所有键值对
for key, value in data.items():
    print(key, value)

from configparser import ConfigParser

config = ConfigParser()
config.read('config.ini')

# 访问特定键的值
value1 = config.get('section1', 'key1')
print(value1)  # 输出：value1

# 遍历所有键值对
for section in config.sections():
    for key, value in config.items(section):
        print(key, value)
