Yes. Here's how to produce one:
gerhard@lara:~$ python
Python 2.4.2 (#2, Sep 30 2005, 21:19:01)
[GCC 4.0.2 20050808 (prerelease) (Ubuntu 4.0.1-4ubuntu8)] on linux2
Type "help", "copyright" , "credits" or "license" for more information.[color=blue][color=green][color=darkred]
>>> s = "\x000"
>>> s[0] == chr(0)[/color][/color][/color]
True[color=blue][color=green][color=darkred]
>>>[/color][/color][/color]

this works too :)
[color=blue][color=green][color=darkred]
>>> s = '\x001'
>>> s[0] == chr(0)[/color][/color][/color]
True[color=blue][color=green][color=darkred]
>>> s = '\x00abc'
>>> s[0] == chr(0)[/color][/color][/color]
True
i think it would be more clear not to use 3 digits for this example since \x
only uses the next two numbers, not 3.
[color=blue][color=green][color=darkred]
>>> s = '\x00'
>>> s[0] == chr(0)[/color][/color][/color]
True

That's a little excessive when:
[color=blue][color=green][color=darkred]
>>> s = '\0'
>>> s[0] == chr(0)[/color][/color][/color]
True
Oh, and to reassure the OP that that null really is *in* the string:
[color=blue][color=green][color=darkred]
>>> len(s)[/color][/color][/color]
