检出图书管理系统中的图书

Question

我正在为基本图书馆管理系统编写代码，我有一个ID号，书名和作者的txt文件。我已经到了登录系统请求身份证号码等阶段，我可以搜索书籍。现在我需要把它做出来，以便我可以查看这本书...我已经得到了它，所以它会搜索这本书，但是我需要将ID号码附加到txt文件中的正确书本上。我已经知道它只是附加到最后一个对象。任何指针都会很有帮助。谢谢。

用于搜索图书本次代码...

while True: 
    n=float(raw_input('Please enter your ID ')) 
    if n in range (1000,10000): 

    break 
print 'ID is incorrect, please try again' 


with open("txt.txt") as searchfile: 
    found = False 
    while not found: 
     b=str(raw_input('please enter a book ')) 
     if b == '': 
     break # allow the search-loop to quit on no input 
     for line in searchfile: 
      if b in line: 
       print line 
       found = True 
       break 
     else: 
      print 'Please try again' 
      searchfile.seek(0) # reset file to the beginning for next search 


searchfile.close() 

这所有的作品^^^然后我得检查出书和得到这个下面的代码：

find_book=[] 
    with open('txt.txt') as input_file: 
     lines = [line.rstrip().split('\t') 
       for line in input_file.readlines()] 



if(find_book('0',3))==0: 
    print 'availabile'

这是图书馆管理程序，我最初拿一些书，一些学生和两位图书馆员。图书管理员只能查看书籍的详细信息，学生的详细信息，他们只能添加或删除学生登录信息。学生在那里登录详细信息，并从现有书籍中收集书籍，并返回所拍的书籍。如果学生收集书籍，书籍详细信息会附加到派发的列表中并从可用列表中删除。
