Adds Custom ToString Method to API Classes

[AlexCatarino]

Expected Behavior

Be able to visualize the results from API calls with ToString method. It's particularly helpful in Jupyter Notebooks.

Actual Behavior

The string representation looks like this:

<QuantConnect.Api.Compile object at 0x7f7082330978>

Potential Solution

Implement Custom ToString

Hi, can I take it ?

Hey @MaxTube-dot! yes please go ahead, suggest just implementing one at the time with it's unit test 👍

Hi @AlexCatarino, do you mean ToString Method should be added to this document below? https://github.com/QuantConnect/Lean/blob/master/Api/Api.cs What steps did you go through to get the message <QuantConnect.Api.Compile object at 0x7f7082330978>

Hey @jfweonc! The ToString methods should be added for the objects returned by the Api methods, can see them at https://github.com/QuantConnect/Lean/tree/master/Common/Api. Suggest taking them one at the time.

This is just the default to string implementation that python takes from a C# class. If ToString was implemented it would use it instead
