我有一个包含参与者和participantsIdentities数组属性的对象。这两个属性都有participantId属性。如何将它们联系起来？

# 创建一个空字典用于存储参与者对象
participants = {}

# 假设有一个包含参与者和participantsIdentities数组属性的对象
data = {
  "participants": [
    {"participantId": 1, "name": "Alice"},
    {"participantId": 2, "name": "Bob"},
    {"participantId": 3, "name": "Charlie"}
  ],
  "participantsIdentities": [
    {"participantId": 1, "identity": "alice@example.com"},
    {"participantId": 2, "identity": "bob@example.com"},
    {"participantId": 3, "identity": "charlie@example.com"}
  ]
}

# 将参与者对象存储在字典中，以participantId作为键
for participant in data["participants"]:
  participants[participant["participantId"]] = participant

# 遍历participantsIdentities数组，将参与者对象与身份信息联系起来
for identity in data["participantsIdentities"]:
  participantId = identity["participantId"]
  participant = participants[participantId]
  participant["identity"] = identity["identity"]

# 打印结果
for participant in data["participants"]:
  print("Participant:", participant["name"])
  print("Participant ID:", participant["participantId"])
  print("Identity:", participant["identity"])
  print()

Participant: Alice
Participant ID: 1
Identity: alice@example.com

Participant: Bob
Participant ID: 2
Identity: bob@example.com

Participant: Charlie
Participant ID: 3
Identity: charlie@example.com
