Using sid() fails from notebook

Getting Started 
print sid(24)

... Works in Algo but fails in Notebook with: NameError: name 'sid' is not defined

So maybe for the notebook I need to import sid, but in Algo it has been done automatically?

https://www.quantopian.com/help#api-sid doesn't give any clue.

print sid.__module__  # gives: algoproxy

Searching https://www.quantopian.com/help for algoproxy yields nothing and trying stuff like from quantopian.algoproxy import sid fails.

Cannot import inspect as Q doesn't offer that module (https://docs.python.org/2/library/inspect.html).

Rats.

Try "symbols" instead of sid.

That works, thanks!

It is unexpected behaviour though, this symbols is not the same as https://www.quantopian.com/help#api-symbols

Looking at https://www.quantopian.com/help#api-other -> "Within your algorithm, there are some other methods you can use:" -- I suppose that implies the IDE.

Ok so assuming that above link lists functions available to IDE only, somewhere there should be a section listing functions available to Notebooks only, which would contain the symbols function. Is there? How did you find it? Maybe there is some doc resource I haven't found yet...

Hi Pi,

You're right that the API differs between the IDE and Research. The IDE API is documented under the "API Documentation" header. The Research API is documented under the "Research Environment API" header. You can jump to these headers using the links in the sidebar. Please let me know if you need any help navigating the documentation.
