无法打开Python搁置对象

Question

在Python中尝试使用shelve时会遇到很多问题。

不久前我刚刚创建了一个新的工具架*.dbm对象，但是现在，我得到了一个错误：

import shelve
TESTING = shelve.open('C:\Users\dtruman\Documents\PROJECTS\testing.dbm','c',writeback=True)

Python返回以下隐含错误：

Traceback (most recent call last):
  File "<pyshell#7>", line 1, in <module>
    TESTING = shelve.open('C:\Users\dtruman\Documents\PROJECTS\testing.dbm','c',writeback=True)
  File "C:\Program Files (x86)\Python_2-7-11\lib\shelve.py", line 243, in open
    return DbfilenameShelf(filename, flag, protocol, writeback)
  File "C:\Program Files (x86)\Python_2-7-11\lib\shelve.py", line 227, in __init__
Shelf.__init__(self, anydbm.open(filename, flag), protocol, writeback)
  File "C:\Program Files (x86)\Python_2-7-11\lib\anydbm.py", line 85, in open
return mod.open(file, flag, mode)
  File "C:\Program Files (x86)\Python_2-7-11\lib\dbhash.py", line 18, in open
return bsddb.hashopen(file, flag, mode)
  File "C:\Program Files (x86)\Python_2-7-11\lib\bsddb\__init__.py", line 364, in hashopen
d.open(file, db.DB_HASH, flags, mode)
DBError: (14, 'Bad address')

看起来我正在尝试执行一个非常简单的操作，但是出于某种原因，Python并不喜欢它。

文件路径字符串中"\t“可能被解释为制表符。尝试将文件路径设置为原始字符串：

TESTING = shelve.open(r'C:\Users\dtruman\Documents\PROJECTS\testing.dbm','c',writeback=True)
