1. 格式類型是什么？

• case:concept:name (案例ID) - 必須是字符串類型
• concept:name (活動名稱) - 字符串類型
• time:timestamp - 必須是datetime類型

2. 如何修改？

    data['case:concept:name'] = data['case:concept:name'].astype(str)data['concept:name'] = data['concept:name'].astype(str)data['time:timestamp'] = pd.to_datetime(data['time:timestamp'])
