Python.InvokeModule

Syntax

InvokeModule(ModuleId: String, FunctionName: String, Params: Array): Variant;

Parameters

ModuleId. Python module identifier in repository.

FunctionName. Name of executed function. Parameter value is case sensitive.

Params. Array of parameter values sent to function.

Description

The InvokeModule method executes the function stored in a Python module and returns result of its work.

Comments

If the executed function does not contain input parameters, do not specify Params. Values of parameters in Params can be sent as a separate array or enumerated via a comma. Simple type values, such as, String, Char, Integer, Double, Decimal, Currency, Boolean (types str, int, float, bool in Python), are sent according to Fore syntax without transformations. The Null value corresponds to the None value in the Python language. If a Python function receives an object of any Python class, list, or tuple as an input parameter, create the corresponding object using one of the Fore classes: PythonClassObject, PythonList, PythonTuple.

If the function has parameters with default values, and it is required to send only part of parameters, use named parameters. Named parameters are implemented by the PythonParameter class. Create parameters with required names, set value for them and send them to the Invoke method.

Example

Executing the example requires that the repository contains a Python module with the MOD_PYT identifier. The following class is implemented in the module:

def summXY(x, y):
return x + y

Add links to the Python system assembly.

Sub UserProc;
Var
    Result: Variant;
Begin
    Result := Python.InvokeModule("MOD_PYT", "summXY", 100, 500);
    Debug.WriteLine(Result);
End Sub UserProc;

On executing the example a function in the Python language is executed that sums two numbers sent in parameters. The result of function execution is displayed in the development environment console.
