tpythondelphivar Creation of TPythonDelphiVar on-the-fly don't works as expected.

[Juan C.Cilleruelo 10]

I'm having the following problem with TPythonDelphiVar component.

I use the next method to create one instance of this component on-the-fly:

function TForm1.NewVariable(AVarName :string):TPythonDelphiVar;
begin
   Result := TPythonDelphiVar.Create(nil);
   Result.Engine    := PythonEngine;
   Result.Module    := '__main__';
   Result.VarName   := AVarName;
   Result.Initialize;
end;

I have a Private variable declared in the TForm1class, like this:

public
    FVariable :TPythonDelphiVar;

And I use the next code to create on-the-fly my variable QUANTITY:

FVariable := NewVariable('QUANTITY');
FVariable.Value := 1.0;

All seems ok, but when I execute the program, and I try to print the value of QUANTITY:

(Phyton script).

print(QUANTITY)

I get the following message error in a message error window: "NameError: 'QUANTITY' is not defined. " 

And in the output memo of the PythonEngine, the next one:

Traceback (most recent call last):
  File "<string>", line 13, in <module>
NameError: name 'QUANTITY' is not defined

I can't understand why creating the TPythonDelphiVar on-the-fly doesn't work while creating the same component in design time works well. 

Do you understand what the problem is?

The same problem with the class TPythonModule.  If I create in visual form, including it on a form, it works well. If I create it on the fly, the next statements 

 

FPythonModule.AddDelphiMethod('ComponentCount', ComponentCount, 'ComponentCount');
FPythonModule.AddDelphiMethod('GetPRICE'      , GetPRICE      , 'GetPRICE'      );

 

run, but when I try to use ComponentCount in my Python Script, does not exist. 

 

what's happening?
