convert ascii escapes into binary form

[Hans-Peter Jansen]

Hi Pythonistas,

I need to convert ascii escapes into binary form, e.g.:
\f -> ^L
\033@\x1bk\000 -> ^[@^[k^@

(rvalues in terminal representation)

Any idea, how to do this most elegantly in python?
Do I really need to do a search n'replace orgy, combined with
regex for this task?

TIA,
Pete

In [11]: s = '\\f'

In [12]: s.decode('string_escape')
Out[12]: '\x0c'

That did the trick, thanks a lot, Peter. Unfortunately, on the
target system, there's still python 2.0 running :-( Looks like
I've to bite the apple..

Sorry, Robert. That's the price to pay for doing multiple replies at
the same time. Mea culpa..
