Hello,
My question is a bit of a novice question because I am kind of new to Delphi and I just started using this library. I am just trying to pass 2 arguments from the python version of a function to the delphi version of the function. I have been using the Demos (demo 3) and the book linked in the readme in the P4D Git repo, but I am a little stuck/confused. I was able to get my really simple Python script to run if I pass 1 argument but if I try to pass 2 arguments to my function in the Python script this is the error I get:
QuoteTraceback (most recent call last):
File "<string>", line 3, in <module>
TypeError: read_AP_register() takes exactly 1 argument (2 given)Here are the snippets of code:
Quote//Delphi Code:
procedure TForm1.PythonModule1Events0Execute(Sender: TObject; PSelf,
Args: PPyObject; var Result: PPyObject);
Var
arg1 : LongWord;
arg2 : LongWord;
output: LongWord;
begin
With GetPythonEngine
Do
Begin
if PyArg_ParseTuple(Args, 'i:read_AP_register', @arg1, @arg2) <> 0
Then
begin
output := read_AP_register(arg1, arg2);
Result := PyLong_fromLong(output);
end
Else
begin
Result := Nil;
end;
End;
end;
//this is just an nonsense example function
function read_AP_register (arg1, arg2 : LongWord): LongWord;
begin
result := arg1 - arg2;
end;
//Python Scriptfrom delphi_module import read_AP_register
result = read_AP_register(15, 10)
print(result)
If anyone has any suggestions or tips that could help out that would be really awesome!
Thanks!
