如何从具有重复值的列表中获取最新日期和TotalEnrollments

# 假设数据列表为data_list，每个数据项包含日期和TotalEnrollments字段
data_list = [
    {"date": "2022-01-01", "TotalEnrollments": 100},
    {"date": "2022-02-01", "TotalEnrollments": 200},
    {"date": "2022-02-01", "TotalEnrollments": 300},
    {"date": "2022-03-01", "TotalEnrollments": 400},
]

# 步骤1：根据日期进行排序
sorted_data = sorted(data_list, key=lambda x: x["date"], reverse=True)

# 步骤2：找到最新日期的数据
latest_data = sorted_data[0]

# 步骤3：获取最新日期数据的TotalEnrollments值
latest_total_enrollments = latest_data["TotalEnrollments"]

# 步骤4：获取所有最新日期的数据
latest_data_list = [data for data in sorted_data if data["date"] == latest_data["date"]]

print("最新日期的TotalEnrollments值：", latest_total_enrollments)
print("所有最新日期的数据：", latest_data_list)
