B4J Code Snippet [PyBridge] Convert Python object to dict / map

This methods extracts a list of fields from a Python object and creates a dict (Python equivalent to Map) with the field names as keys and the values.
It is useful when the relevant fields are serializable.

Private Sub ObjectToDict (Obj As PyWrapper, Fields As List) As PyWrapper
    Dim entries As List = B4XCollections.CreateList(Null)
    For Each key As String In Fields
        entries.Add(Array(key, Obj.GetField(key)))
    Next
    Return Py.Builtins.Run("dict").Arg(entries)
End Sub

Usage example:

Public Sub RunCommand (Command As String) As ResumableSub
    Wait For (mConn.RunAwait("run", Array(Command), Null)) Complete (Result As PyWrapper)
    'Result is a Python object that can't be serialized directly, so we extract the fields:
    Wait For (ObjectToDict(Result, Array("stdout", "stderr", "exit_status")).Fetch) Complete (Result As PyWrapper)
    Return Result
End Sub

An alternative and more powerful option is to add a converter as demonstrated here: https://www.b4x.com/android/forum/threads/pybridge-non-linear-regression-with-scipy.166985/#content
