I am trying to read some byte data as a string then using a library to

My table contains:
\x00\x00,0000
\x01\x00,0000
......
The program errors out. How can I fix/overide this backslash issue.
What does `errors out` mean?
It won't find two zero bytes. What you give at the `eleFind()` call are
just *two* characters with a byte value of zero:
In [116]: len('\x00\x00')
Out[116]: 2
In [117]: print '\x00\x00'
In [118]: len('\\x00\\x00')
Out[118]: 8
In [119]: print '\\x00\\x00'
\x00\x00
The backslash has a special meaning in string literals. If you don't want
this meaning, you have to escape it with another backslash.
