How to create regex for the expression starts with and ends with curly braces?

Question

I want to find a string in a text file which starts with '{"ABC":' and ends with '}' .

So far I have tried following:

re.findall('^{\"ABC(.)*$}', text_string, re.MULTILINE)

But it's not working as expected.

Answer 1

If you want to capture the whole string:

re.findall('({"ABC":.*})', text_string, re.MULTILINE)

If you want to capture just the contents:

re.findall('{"ABC":(.*)}', text_string, re.MULTILINE)

Of course, this can be useful to extract JSON-like structures from plain text data, but do not use regex for parsing any sort of structured/multi-level data - use a parser created for it, like the built-in module json for JSON.
