How do you parse a string enclosed in Curly Braces?
For instance:
x = "{ABC EFG IJK LMN OPQ}"
I want to do x.split('{} ') and it does not work. Why does it not work
and what are EXCEPTIONS to using the split method?
Other people have already done this bit :-)
That I want to split based on '{', '}' and WHITESPACE.
This is not the same as what you first said, and I have a horrid feeling
you're trying to conflate two steps into one. That way lies madness.
First, a question. Is 'x' truly a good representation of your original
data? Could it instead look more like:
x = "Ignore this {but not this} and completely forget about this"
Can you have braces legitmately lying around in the string, escaped
somehow:
x = r"{Parse including the \} escaped close brace}"
Can you have nested braces, and what are you supposed to do with them:
x = "{Some text to parse {as well as an aside} and so on}"
Parsing is not an entirely trivial subject, particularly when users
can futz about with the strings you're parsing. That's one reason there
are so many lexers and parsers out there!
