仅读取文本文件的第一行

Question

我有一个名为“ paintingJobs”的文本文件。 数据如下所示：

E5341,21/09/2015,C102,440,E,0
E5342,21/09/2015,C103,290,A,290
E5343,21/09/2015,C104,730,N,0
E5344,22/09/2015,C105,180,A,180

我编写了一个程序，该程序只能找到第一个条目，但找不到第一行以外的任何数据（我认为这与Python有关，在用户名前面包含/ n）该程序看起来像这样。

def ASearch():
    print("Option A: Search for an estimate")
    print("Please enter the estimate number: ")
    estimateNumber = str(input())
    file = open("paintingJobs.txt", "r")
    paintJobs = file.readlines()
    file.close()
    length = len(paintJobs)
    paintData = []
    for line in paintJobs:        
        estNumber, estDate, CustID, FinalTotal, Status, AmountPaid =      line.split(",")
        if estimateNumber == estNumber:            
            print("Estimate number: ", estNumber)
            print("Customer ID: ", CustID)
            options()#this is a function in a for a different part of the program that works fine
        else:
            print("You have entered an incorrect estimate number; please try again")
            ASearch()

如何使程序读取EG E5342列表中的第二个条目（并返回其值）（非常感谢您的帮助）
