我正在为基本的图书馆管理系统编写代码，我有一个用于ID号，书名和作者的txt文件。我已经到了我有登录系统的阶段，要求提供身份证号等，我可以搜索书籍。现在我需要制作它以便我可以查看这本书...我已经得到它所以它会搜索这本书然后我需要将ID号附加到txt文件中的正确书籍上。我已经得到它，它只是附加到最后一个对象。任何指针都会有很大的帮助。谢谢。
提供搜索图书的代码......
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()
这一切都有效^^^然后我要检查书籍并得到以下代码：
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'

这是图书馆管理计划，我最初拿了一些书，一些学生和两个图书管理员。图书馆员只能查看书籍详细信息，学生详细信息，他们只能添加或删除学生登录。学生使用详细信息登录并从可用书籍中收集书籍，并返还所需的书籍。如果学生收集该书，则书籍详细信息将附加到已发送的列表中，并从可用列表中删除。
