Is it possible for python strings to contain a zero byte?

Yes. Here's how to produce one:

s = "\x000"
s[0] == chr(0) True

s = "\x000"
s[0] == chr(0)

True

this works too

>>> s = '\x001'
>>> s[0] == chr(0) True
>>> s = '\x00abc'
>>> s[0] == chr(0)

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.

>>> s = '\x00'
>>> s[0] == chr(0)

True

s = '\x00'
s[0] == chr(0)

True

That's a little excessive when:

s = '\0'
s[0] == chr(0)

True

Oh, and to reassure the OP that that null really is *in* the string:
