All,

I'm a quantConnect python beginner and having a hard time to find simple to understand examples as well as quantConnect pyton documentation. The quantConnect documentation is a good introduction but it doesn't really have concerete examples.

I've read here I can find some examples:

github.com/QuantConnect/Lean/tree/master/Algorithm.Python 

Now, I'm looking at this example:

github.com/QuantConnect/Lean/blob/master/Algorithm.Python/DailyAlgorithm.py

could somebody answer the following questions please:

- what is Field.SevenBar? and where can I find an explanation if I had to find an answer by myself?

- what is lastAction? Where do I learn how to use it?

- what does it mean "data.ContainsKey?

I'm quite concerned in regards of the current available documentation. I'm trying to move from quantopian to QC but it doesn't seem that simple...

Thanks,
Andrea
