The pipline results returns a dataframe with an equity object in the index.
And I need to use Quantopian's symbol name to filter on a security certain securities.
For example I want to filter on securities with a quantopian's symbol starting by "AB".
any way to achieve it?
also if I could just retrieve the Q's symbol (not morningstar) in a column, that could help as I'd use the "startswith" ...?
How can I filter on an equity object using Q's symbol name?
Take a look at StaticAssets in this thread https://www.quantopian.com/posts/using-a-specific-list-of-securities-in-pipeline

Thanks Dan.
Let me detail a bit more what I wanted to achieve.
from the list of securities, I need to identify the "warrants". and I think the Warrants in quantopian have a symbol of "ABC_W".
so if I can filter on the symbol of securities, I thought I would be able to do something like "%_W" to filter on all the securities with symbols ending with W.
I know there is ".endwith" which could be used with morningstar fondamental data, but I am not sure how to do something similar with the equity object used to index the dataframe returned by the pipline.
I hope that's clarifying a bit more what I am trying to achieve, and many thanks for your guidance.
Maybe try something like this...
# Add a new column for the symbol to the output dataframe
# The stock symbol can be gotten from the 'symbol' attribute of the equity object in the index
pipe_output["symbol"] = [equity.symbol for equity in pipe_output.index.values]
# Filter the pipe_output to only those equities which end with '_W'
# Presumably the warrants all end with '_W' so this will be a dataframe of just warrants
just_warrants = pipe_output[pipe_output.symbol.str.endswith('_W')]
Attached is a notebook which shows this in action.
