I have a content which is really complicated.
In the content there is a JSON key that I need its value. Consider the content below:

"THE_KEY": "THE_VALUE_WHICH_DIFFERS_EVERYTIME"

How can I access the value of the key with Regex in Python? Consider the key is always the same but the value changes all over the time. Thanks!

What I have tried:

I have tried ways which are not related to the question and I understood I should use this way.

Why are you using regex? Python has excellent support for JSON.

I would use built in JSON support, it's much more flexible.

But ... if you must use a Regex, you could try:

(?<=\"THE_KEY\"\s*:\s*\").+?(?=\")

If you are going to play with regular expressions, then get a copy of Expresso[^] - it's free, and it examines and generates Regexes.
