When you execute code, say with ExecString, CheckError is called at the end which on exception updates PythoneEngine.Traceback. and raises a suitable EPythonError descendent exception. type
EPythonError = class(Exception)
public
EName : string;
EValue : string;
end;
TTracebackItem = class
public
FileName : string;
LineNo : Integer;
Context : string;
end;
TPythonTraceback = class
public
property ItemCount : Integer read GetItemCount;
property Items[ idx : Integer ] : TTracebackItem read GetItem;
property Limit : Integer read FLimit write FLimit;
end;So what you typically do is: try
ExecString(Code, FileName);
except
on E: EPythonError do
begin
// Inspect E.EName and E.EValue
// Inspect the GetPythonEngine.Traceback
end;
end |
