这是一段 Python 代码，但是您并没有提出问题。请问您需要我帮您分析这段代码的作用吗？这段代码的主要作用是爬取高校信息，包括高校名称、内容、是否为 985/211 高校、软科排名、类型、学校性质、省份名称、城市名称、地址、专业等级分数线。其中，通过循环遍历获取专业等级的分数线，并根据指定的条件进行筛选。

ProgramModelEntities = _migrateRepository.GetAllWithNoTrackingAsync<ProgramModelEntity>().ToList(); Programmes = ProgramModelEntities.Select(program => { CProgramme p = new CProgramme() { Id = new Guid(program.Id), Name = program.Name, SchoolId = SQIConstants.SYS_School_ID, Description = program.Description, CreatedById = String.IsNullOrEmpty(program.CreatedBy) ? new Guid("e306ca07-a21b-40fd-935a-343cfe369001") : new Guid(program.CreatedBy), CreatedTime = program.CreatedOn == null ? new DateTime().Ticks : program.CreatedOn.Value.Ticks, ModifiedById = String.IsNullOrEmpty(program.ModifiedBy) ? new Guid("e306ca07-a21b-40fd-935a-343cfe369001") : new Guid(program.ModifiedBy), ModifiedTime = program.ModifiedOn == null ? new DateTime().Ticks : program.ModifiedOn.Value.Ticks, Duration = 1 }; if (!String.IsNullOrEmpty(program.ProgramAdmins)) { var admins = program.ProgramAdmins.Split(";"); ResourceAccesses.Add(admins.Select(admin => new CResourceAccess() { Id = Guid.NewGuid(), UserId = new Guid(admin), RoleType = RoleType.ProgrammeAdmin, ResourceId = new Guid(program.Id), ResourceLevel = ResourceLevel.Programme } ).ToList()); } ResourcesList.Add(new CResources { Id = new Guid(program.Id), ResourceLevel = ResourceLevel.Programme, SchoolId = SQIConstants.SYS_School_ID, ProgrammeId = new Guid(program.Id), }); return p; } ).ToList(); 优化下这段代码

以下是对这段代码的一些优化建议：

1. 使用异步方法来获取数据，可以提高性能。例如，可以使用 `ToListAsync()` 替代 `ToList()`。

2. 使用 LINQ 的 Select 方法来进行对象的转换，可以让代码更简洁易读。例如，可以使用如下的代码替代 `ProgramModelEntities.Select()`：

Programmes = await _migrateRepository.GetAllWithNoTrackingAsync<ProgramModelEntity>()
    .Select(program => new CProgramme
    {
        Id = new Guid(program.Id),
        Name = program.Name,
        SchoolId = SQIConstants.SYS_School_ID,
        Description = program.Description,
        CreatedById = String.IsNullOrEmpty(program.CreatedBy)
            ? new Guid("e306ca07-a21b-40fd-935a-343cfe369001")
            : new Guid(program.CreatedBy),
        CreatedTime = program.CreatedOn?.Ticks ?? new DateTime().Ticks,
        ModifiedById = String.IsNullOrEmpty(program.ModifiedBy)
            ? new Guid("e306ca07-a21b-40fd-935a-343cfe369001")
            : new Guid(program.ModifiedBy),
        ModifiedTime = program.ModifiedOn?.Ticks ?? new DateTime().Ticks,
        Duration = 1
    })
    .ToListAsync();

3. 对于资源列表和资源访问列表的操作，可以使用 LINQ 的 SelectMany 方法和 Where 方法来替代 foreach 循环。例如，可以使用如下的代码替代 `if (!String.IsNullOrEmpty(program.ProgramAdmins))` 和 `ResourcesList.Add()`：

var programmeAdmins = program.ProgramAdmins?.Split(';');

if (programmeAdmins?.Any() == true)
{
    ResourceAccesses.AddRange(programmeAdmins
        .Select(admin => new CResourceAccess
        {
            Id = Guid.NewGuid(),
            UserId = new Guid(admin),
            RoleType = RoleType.ProgrammeAdmin,
            ResourceId = new Guid(program.Id),
            ResourceLevel = ResourceLevel.Programme
        }));
}

ResourcesList.AddRange(programmeAdmins?.Select(admin => new CResources
{
    Id = new Guid(program.Id),
    ResourceLevel = ResourceLevel.Programme,
    SchoolId = SQIConstants.SYS_School_ID,
    ProgrammeId = new Guid(program.Id),
}) ?? Enumerable.Empty<CResources>());

综上所述，以下是经过优化后的代码：

Programmes = await _migrateRepository.GetAllWithNoTrackingAsync<ProgramModelEntity>()
    .Select(program => new CProgramme
    {
        Id = new Guid(program.Id),
        Name = program.Name,
        SchoolId = SQIConstants.SYS_School_ID,
        Description = program.Description,
        CreatedById = String.IsNullOrEmpty(program.CreatedBy)
            ? new Guid("e306ca07-a21b-40fd-935a-343cfe369001")
            : new Guid(program.CreatedBy),
        CreatedTime = program.CreatedOn?.Ticks ?? new DateTime().Ticks,
        ModifiedById = String.IsNullOrEmpty(program.ModifiedBy)
            ? new Guid("e306ca07-a21b-40fd-935a-343cfe369001")
            : new Guid(program.ModifiedBy),
        ModifiedTime = program.ModifiedOn?.Ticks ?? new DateTime().Ticks,
        Duration = 1
    })
    .ToListAsync();

var programmeResources = Programmes.SelectMany(programme => new[]
{
    new CResources
    {
        Id = programme.Id,
        ResourceLevel = ResourceLevel.Programme,
        SchoolId = SQIConstants.SYS_School_ID,
        ProgrammeId = programme.Id
    }
});

var programmeAdminResources = Programmes.SelectMany(programme =>
{
    var programmeAdmins = programme.ProgramAdmins?.Split(';');
    
    return programmeAdmins?.Select(admin => new CResourceAccess
    {
        Id = Guid.NewGuid(),
        UserId = new Guid(admin),
        RoleType = RoleType.ProgrammeAdmin,
        ResourceId = programme.Id,
        ResourceLevel = ResourceLevel.Programme
    }) ?? Enumerable.Empty<CResourceAccess>();
});

ResourcesList.AddRange(programmeResources);
ResourceAccesses.AddRange(programmeAdminResources);

前端传来的搜索条件 1. pageNum: 1 2. pageSize: 20 3. schoolId: 12 4. clockTime_begin: 2023-08-02 5. clockTime_end: 2023-08-03 ``` <select id="selectAttStudentRecordList" parameterType="AttStudentRecord" resultMap="AttStudentRecordResult"> <include refid="selectAttStudentRecordVo"/> <where> <if test="schoolId != null "> and school_id = #{schoolId}</if> <if test="parentId != null "> and parent_id = #{parentId}</if> <if test="studentId != null "> and student_id = #{studentId}</if> <if test="stuName != null and stuName != ''"> and stu_name like concat('%', #{stuName}, '%')</if> <if test="stuNo != null and stuNo != ''"> and stu_no = #{stuNo}</if> <if test="cardNo != null and cardNo != ''"> and card_no = #{cardNo}</if> <if test="clockType != null "> and clock_type = #{clockType}</if> <if test="imgUrl != null and imgUrl != ''"> and img_url = #{imgUrl}</if> <if test="clock_time != null" > and clock_time =#{clockTime}</if> <if test="channelName != null and channelName != ''"> and channel_name like concat('%', #{channelName}, '%')</if> <if test="deviceId != null "> and device_id = #{deviceId}</if> <if test="tenantId != null "> and tenant_id = #{tenantId}</if> and del_flag = 0 </where> </select> 我在xml文件中的where要怎么写

你可以根据前端传来的搜索条件，在XML文件的`<where>`标签中编写相应的条件语句。以下是根据你提供的搜索条件示例的XML代码示例：

<select id="selectAttStudentRecordList" parameterType="AttStudentRecord" resultMap="AttStudentRecordResult">
    <include refid="selectAttStudentRecordVo" />
    <where>
        <if test="schoolId != null ">and school_id = #{schoolId}</if>
        <if test="clockTime_begin != null ">and clock_time &gt;= #{clockTime_begin}</if>
        <if test="clockTime_end != null ">and clock_time &lt;= #{clockTime_end}</if>
        and del_flag = 0
    </where>
</select>

以上示例中，根据前端传来的搜索条件，我仅添加了`schoolId`和`clockTime`的判断条件。你可以根据需要添加其他条件，如`pageNum`、`pageSize`等。

请注意，示例中使用了`&gt;=`和`&lt;=`来表示大于等于和小于等于的比较操作符，这是因为XML文件中需要使用实体编码来表示特殊字符。

希望这能帮到你！如果有任何进一步的问题，请随时问我。
