问题描述
我已将代码更改为：
print '\n'
search = raw_input("For which account are you searching: ")
f = shelve.open("passwords.dat")
for line in f:
if search in f:
passwrd = f[search]
entry = passwrd[0]
f.close()
print line
print '\n'
print "I'm sorry we could not find any account related to " + search
print '\n'
f.close()
现在，它将不接受任何正确的帐户并释放此错误：
'int' object has no attribute 'has_key'
为什么现在我收到此消息？
File "E:\password.py", line 98, in program_start
find_account()
File "E:\password.py", line 36, in find_account
if search in f:
File "C:\Python24\lib\shelve.py", line 107, in __contains__
return self.dict.has_key(key)
AttributeError: 'int' object has no attribute 'has_key'

搁置将返回单个字典。
因此，据我所知，从中读取多行是没有意义的。
我认为这应该工作：
print '\n'
search = raw_input("For which account are you searching: ")
with shelve.open("passwords.dat") as f:
for passwords in f:
if search in passwords:
password = passwords[int(search)]
entry = passwrd[0]
print passwords
print '\n'
else:
print "I'm sorry we could not find any account related to " + search
print '\n'
