It's very difficult to understand your question, but I'll take a guess at the problem you are facing.
In the API Reference notebook, there is a section describing the get_backtest() method:
The get_backtest function provides programmatic access to the results of backtests run on the Quantopian platform. It takes a single parameter, the ID of a backtest for which results are desired.
You can find the ID of a backtest in the URL of its full results page, which will be of the form:
If you are saying here that the URL above in the last line of the excerpt doesn't work, you are correct. It will never work. That URL is explaining the structure of our URLs so you can find the backtest_id. Once you have the backtest_id you can use get_backtest() effectively.
The strings '' and '' used in the URL are placeholders. In reality each algorithm has a unique identifier.
Take one of my backtests. It has the URL: https://www.quantopian.com/algorithms/5522e99812b9a0e39f0003fa/5522ea0a6d85df0d2d007888
In this case, my algorithm ID is 5522e99812b9a0e39f0003fa
my backtest ID is 5522ea0a6d85df0d2d007888
I hope I've correctly guessed the question you were asking. If I'm off base, just let me know and we'll try to help out further.
