从数组中获取键名，从特定位置获取

const array = { "key1": "value1", "key2": "value2", "key3": "value3" };

// 从数组中获取键名
const keys = Object.keys(array);
console.log(keys); // 输出 ["key1", "key2", "key3"]

// 从特定位置获取值
const index = 1;
const value = array[keys[index]];
console.log(value); // 输出 "value2"

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

# 从数组中获取键名
keys = list(array.keys())
print(keys) # 输出 ["key1", "key2", "key3"]

# 从特定位置获取值
index = 1
value = array[keys[index]]
print(value) # 输出 "value2"
