Simple Doc Test failing without any reason [Help Needed]

[afrobeard]

The following following code fails with the failiure:-


File "test.py", line 27, in __main__.sanitize_number
Failed example:
    sanitize_number('0321-4683113')
Expected:
    '03214683113'
Got:
    '03214683113'


Expected and Got looks the same. The value should verify.  What am I
doing wrong here ?

Thanks in advance. I really appreciate your time.

P.S. I tested this Python2.5 installed on both Ubuntu Hardy Heron and
Windows XP
