New submission from Nicholas Willhite :
I'm really sure this isn't filed correctly. I'm a total noob to this process,
so feel free to redirect me. :)
Bytes can be defined as a function, or a prefixed series. You can prefix a
series with "b" and get the expected data type. You can also use the builtin
functions "bytes" to get the same structure:
bytes('foo\bar', 'utf-8') == b'foo\bar'
True
But there's no builtin function for r'foo\bar' that gives you 'foo\\bar'.
This would be really handy for applications that accept a regular expression.
If that regex was part of the source code, I'd just r'foo\bar' to get the
expected string. Being able to accept something like bytes and do:
data = b'foo\bar'
raw_string(data)
'foo\\bar'
would be really useful for applications that accept a regex as input.
Is there an obvious way to do this that I'm not seeing? Has my google-foo
failed me? Feels like a function that should exist in the stdlib.
Again, really sure I'm not "doing this correctly." So please direct me! :)
Appreciative,
-Nick Willhite
