使用 RegEx 在文件中搜索以使用 Python 查找 ID 及其编号

Question

I am fairly new to regEx and I am completely baffled by it at this point so any help will be greatly appreciated. Sorry if this question is around already, could not find it. All of this is happening in Python

I am trying to do a search inside text file which has some text like:

www.google.com, something, something: something, [{'id': 481, 'name': 'name it needs to match'}]

="1000" t5:someplace="7713" t5:somethingelse="10" t5:someotherthing="10"

it have multiple, very long lines (its a log, essentially).

What I need to do is to find a word "id" with its number by the "name" that it have inside the brackets and keep only the number (or all of it, doesn't matter) so I can put it back into the program (I am trying to create something that already exists trough API and I want to use Id of the existing thing to use it later on)

I am pretty sure I can do the slicing after I have filtered ID with its number but I am struggling to write RegEx that can find "Id" and its number by NAME.

Anyone have some insight? any advice let alone piece of code would be an immense help. I concur that it is completely possible there is far easier solution that I am not seeing and I will be grateful if anyone can tell me said solution, I am here to learn as much as possible:)

PS: position of the "name" variable is almost always the same or at least very close to it, is there a way to use RegEx to say find the "name" and then slice everything around the "name" for approx 15-20 characters? I could then filter out the number only since I will know it is there.

Answer 1

Try

'id': (\d+),.*?'name': '([^']*)'

This way you'll get the ID in capture group 1 and the name in capture group 2.
