Summary: csv module does not handle '\x00'
Initial Comment:
The following from an interactive session failed instead of just returning the
'\x00':
>>> r = csv.reader(['a,line,with,a,null,\x00,byte'])
>>> r.next()
Traceback (most recent call last):
File "<pyshell#31>", line 1, in -toplevel-
r.next()
Error: string with NUL bytes
>>>

I've been using the csv module to parse data coming from a serial port of
a lab instrument. Occasionally the instrument transmits a lone /x00 (maybe
when the power cycles, I'm not sure). Anyhow, I'm now using a try-except
statement to catch the error.
I guess my answer to your question is that I think the module should
handle whatever string you pass it. Is there a specific reason not to
handle /x00?

Why do you think a CSV reader should support null bytes?
CSV is a text format, not a binary one.
