Python新手遇End of file reached错误求助（附Arm类代码）

嘿，作为Python新手碰到这个问题真的超正常，别慌！咱们来拆解一下问题根源，然后搞定它～

错误原因 #

你看到的End of file reached错误，本质是代码不完整就结束了。从你贴的代码片段能明显看出来：

• self.RequesterEmailId=Req...这里是截断的，没有把属性赋值写完
• 整个__init__方法的代码没有写完，Python靠缩进区分代码块，没写完的话解释器不知道什么时候结束这个方法
• 类的定义也因为方法没写完，处于未完成状态

修正后的完整代码示例 #

我帮你把截断的部分补全（假设你原本是要把参数对应赋值给实例属性），确保代码结构完整：

class Arm(object): 
    def __init__(self, SNo, ActivityDate, RequesterTeam, RequesterSignumId, RequesterEmailId, Circle, Customer, Technology, WOType, ProblemTitle, ActivityTypeorEqType, SiteID, BSCFACID, EngineerName, EngineerSignum, DetailDescriptionOfActivityToBePerformed, TimelineforActivityCompletion, WOIDbyWFM ): 
        self.SNo = SNo 
        self.ActivityDate = ActivityDate 
        self.RequesterTeam = RequesterTeam 
        self.RequesterSignumId = RequesterSignumId 
        self.RequesterEmailId = RequesterEmailId
        self.Circle = Circle
        self.Customer = Customer
        self.Technology = Technology
        self.WOType = WOType
        self.ProblemTitle = ProblemTitle
        self.ActivityTypeorEqType = ActivityTypeorEqType
        self.SiteID = SiteID
        self.BSCFACID = BSCFACID
        self.EngineerName = EngineerName
        self.EngineerSignum = EngineerSignum
        self.DetailDescriptionOfActivityToBePerformed = DetailDescriptionOfActivityToBePerformed
        self.TimelineforActivityCompletion = TimelineforActivityCompletion
        self.WOIDbyWFM = WOIDbyWFM

新手小提示 #

• 写Python类的时候，一定要确保每个方法的缩进块都写完，所有属于这个方法的代码都要缩进正确，不能中途截断
• 如果参数太多，建议分成多行写，这样更不容易出错，比如：

class Arm(object): 
    def __init__(
        self, 
        SNo, 
        ActivityDate, 
        RequesterTeam, 
        RequesterSignumId, 
        RequesterEmailId,
        Circle,
        Customer,
        Technology,
        WOType,
        ProblemTitle,
        ActivityTypeorEqType,
        SiteID,
        BSCFACID,
        EngineerName,
        EngineerSignum,
        DetailDescriptionOfActivityToBePerformed,
        TimelineforActivityCompletion,
        WOIDbyWFM 
    ): 
        self.SNo = SNo 
        self.ActivityDate = ActivityDate 
        # 其他属性赋值...

这样排版的代码可读性更高，也能避免因为一行太长不小心截断的问题～
