如何创建一个带有键的重现值值的字典？

// 创建一个带有键的重现值的字典
var dictionary = {
  key1: "value1",
  key2: "value2",
  key3: "value3"
};

// 访问字典中的值
console.log(dictionary.key1); // 输出：value1

// 更新字典中的值
dictionary.key2 = "new value2";

// 遍历字典
for (var key in dictionary) {
  console.log(key + ": " + dictionary[key]);
}

# 创建一个带有键的重现值的字典
dictionary = {
  "key1": "value1",
  "key2": "value2",
  "key3": "value3"
}

# 访问字典中的值
print(dictionary["key1"])  # 输出：value1

# 更新字典中的值
dictionary["key2"] = "new value2"

# 遍历字典
for key in dictionary:
  print(key + ": " + dictionary[key])
