Seeking Help Research

In the research environment,

sid(int)

gives ->NameError: name 'sid' is not defined

symbol('symbol1') is the same.

Does anyone know what is wrong?

symbols('symbol1') works fine.

I also wonder what's wrong

The research (ie notebook) environment and the IDE (ie algo) environment use different methods to fetch asset objects.

In research there is a single method which can lookup an asset, or a list of assets, by either ticker or SID. Check out the docs here. The following are all valid in research:

# enter a single ticker or a list of tickers  
symbols('AAPL')    # returns a single asset  
symbols(['AAPL', 'IBM'])    # returns a list of assets

# enter a single SID or list of SIDs  
symbols(24)   # returns a single asset  
symbols(24, 3766])   # returns a list of assets

# or mix and match tickers and SIDs  
symbols(['AAPL', 3766])

In the IDE there are three separate methods to lookup assets. Check out the docs here. The following are valid in the IDE:

symbol('AAPL')    # returns a single asset  
symbols(['AAPL', 'IBM'])    # returns a list of assets  
sid(24)       # returns a single asset

So, there is nothing wrong, just need to use the methods which are defined for each environment.
