[Black Bullet] how to keycheck for a variable in the response source?

[dark16sider 0]

Let's say I have a variable named Token, It has a value of 123456. When the website response I want to check for this specific value in the response and if it there then it is a success. I tried loliscript, It failed too. The only thing is coding with python. What happens is that loliscript check for  not the actual value 123456. How can I key check with python, it is easier with loliscript.
