更改记录中的字段会产生IndexError

我有一个程序来制作一个地址簿，我希望能够在这样做之前确认对记录的更改 - 如果我搜索姓氏“Peterson”并且有两个条目，我可以选择更改一个，两者，或两者都没有 . 我正在尝试使用基本相同的代码来编辑现有行，或者从程序中删除它 . 我是Python的新手，这是我上课的最后一个项目，我花了四天的时间试图找出哪些不起作用 . 我一直在浏览Stack Overflow并且没有找到一个令人满意的答案我的问题，我确信这是因为我不太了解Python . 我们应该使用创建和重命名临时文件的设置，所以虽然我知道这不是最有效的，但这是我应该做的 .

这就是我所拥有的：

import os
FIRSTNAME = 0
LASTNAME = 1
STREETADDRESS = 2
CITY = 3
STATE = 4
ZIP = 5
TELEPHONE1 = 6
TELEPHONE2 = 7

def modify():
    found = False
    search = input("Enter an item to search for: ")
    new = input("And what should we change it to? ")
    addressbook = open("addressbook.txt", "r")
    temp_file = open("temp.txt", "w")
    line = addressbook.readline()
    while line != "":
            line = line.rstrip("\n")
            lineInfo = line.split("|")
            if lineInfo[1] == search:
                    print("I found it!")
                    print(format(lineInfo[FIRSTNAME], '15s'),format(lineInfo[LASTNAME], '15s'),format(lineInfo[STREETADDRESS], '20s'),format(lineInfo[CITY], '10s'),
                          format(lineInfo[STATE], '5s'),format(lineInfo[ZIP], '10s'),format(lineInfo[TELEPHONE1], '15s')," ",format(lineInfo[TELEPHONE2], '10s'))
                    print()
                    delete = input("change this one? press y for yes.")
                    if delete == "y":
                            found = True
                            lineInfo[1] = new
                            temp_file.write(format(lineInfo[FIRSTNAME])+"|")
                            temp_file.write(format(lineInfo[LASTNAME])+"|")
                            temp_file.write(format(lineInfo[STREETADDRESS])+"|")
                            temp_file.write(format(lineInfo[CITY])+"|")
                            temp_file.write(format(lineInfo[STATE])+"|")
                            temp_file.write(format(lineInfo[ZIP])+"|")
                            temp_file.write(format(lineInfo[TELEPHONE1])+"|")
                            temp_file.write(format(lineInfo[TELEPHONE2])+"|")
                            temp_file.write("\n")
                    else:
                            temp_file.write(line)
                            temp_file.write("\n")
            else:
                    temp_file.write(line)
                    temp_file.write("\n")
            line = addressbook.readline()
    temp_file.close()
    os.rename("temp.txt","newaddress.txt")
    if found:
            print("File has been changed")
    else:
            print("File was not found")
 modify()

现在，当我运行它时，我得到了这个：

Enter an item to search for: Peterson
And what should we change it to? Patterson
I found it!
Edward          Peterson        10 Grand Pl          
Kearny     NJ    90031      383-313-3003      xxx       

change this one? press y for yes.n

change this one? press y for yes.y

if lineInfo[1] == search:

老实说，我完成了这项任务，所以任何和所有的帮助都会产生巨大的影响 . 谢谢，K
