Hello,

I'd like to have control characters in a string to be converted to
their backslash-escaped counterparts. I looked in the encoders section
of the string module but couldn't find anything appropriate. I could
write it myself but I'm sure something of the sort exists. The
hypothetical method "c_escaped()" would work like this:

>>> a="abc\rdef"
>>> print a.c_escaped()
abc\rdef
>>>

Thanks,
robert

print a.encode("string-escape")

Note that there are some wrinkles if the string contains quote marks
(and possibly also if it contains Unicode; I didn't test).

Cheers,
Chris

How could I miss that? I was on that doc page already. Should have
typed "/escape" in the browser ;-)

Thanks,

This is a little different from what you want, but just for the sake of
completeness:

>>> print repr(a)[1:-1]
abc\rdef
