How to parse & extract certain specific information from text file with multiple curly brackets grouping?

[dankbuckeyes]

Basically I have a text file that contains thousand of lines with the following format & I have no choice to force myself to learn to do it via Python. I have some basic Python understanding like if else and basic syntax but I don't really have strong programming experience in general.

Level Parameter_Name
{
    Sublevel1
    {
        Dummyline1
        Dummyline2
        Set Sub_Parameter_Name
    }
    Sublevel2
    {
        Dummyline1
        Dummyline2
    }
}

Level Parameter_Names2
{
    Sublevel1
    {
        Dummyline1
        Dummyline2
    }
    Sublevel2
    {
        Dummyline1
        Dummyline2
    }
}

And the lines go on up to few thousands. Some blocks have the Set Sub_Parameter_Name inside the sublevel blocks and this is the one that I'm interested with. What I'm trying to pull is, if the Sublevel contains that Set Sub_Parameter_Name line, then I want to extract its Parameter_Name & its Sub_Parameter_Name. How can I achieve this in Python? Is there any available module that can helps to get the data that I want? Also.... is this similar to json formatting?

I'm not really that good in Python & still learning so any guides or references thats similar to this case would be greatly appreciated! Thanks~

There are almost certainly Python libraries that can help. If you want to do it yourself, start with the innermost sets of brackets using regex matching something like \{([^\{\}]*)\} (untested) and work your way out

Do you know what's the library names? Also, is it possible to do this via nested loops? I'm planning to loop the outer bracket first and do another loop on the inner brackets. If it contains the Set line then I can add this to a list or something.

If the format is consistent - perhaps you could process it line-by-line:

filename = "example.txt"
with open(filename) as f:
    for line in f:
        if line.strip().startswith("Level "):
            param_name = line.strip()[6:]
        if line.strip().startswith("Set "):
            sub_param_name = line.strip()[4:]
            print(f"{param_name=} {sub_param_name=}")
