No, it didn't. The interpreter showed it, but not with the print command!
>>> x = '\x00\x90\x83H\x11\x0f'
>>> print x
# In my xterm this prints the actual bytes, leaving nothing visible

'\x00' is a length 1 string, containing a single character, hex 0.
The interactive interpreter uses repr() to show the value of things by
default, which returns a form that could be used as a Python literal. It
needs to escape things again. As an example: chr(92) is a backslash... try
>>> print chr(92)

You need to explain this, no idea what you mean. str() of a tuple calls
repr() again on the internal elements, so it has to returns the escaped
