Executes a function present in a Python module.
Example
sPythonModule is string 
<IF ExecutionTarget=Windows>
	// Example of a Python module location
	// The name of the Python module can be different
	sPythonModule = SysDir(srLocalAppData) + ..
				[fSep]+"Programs\Python\Python39\python39.dll"
<ELSE>
	<IF ExecutionTarget=Linux>
	// Example of a Python module location
	// The name of the Python module can be different 
	// (depends on the version of Python, the Linux distribution)
	sPythonModule ="/usr/bin/python/python39.so"
	<END>
<END>
IF NOT PythonInitialize(sPythonModule) THEN
	// In this case, you must: 
	// Check the path 
	// Check that the compilation mode (32/64-bit) matches the runtime mode
	Error("Python initialization error", ErrorInfo())
	RETURN
END
Info(HelloWorldImportedPythonFunction())
// With an imported Python file (.py) in the project that contains:
// def HelloWorldImportedPythonFunction():
//    return "Hello World!";

IF NOT PythonAddPath(fDataDir()) THEN
	Error("Unable to initialize Python path", ErrorInfo())
	RETURN
END
// "python_file.py" must be in the directory
// specified by PythonAddPath. 
// In this example, this directory is the data directory 
Info(PythonExecute("python_file", "HelloWorldPythonFunctionNotImported"))

PythonTerminate()
Syntax
<Result> = PythonExecute(<Module> , <Function> [, <Parameter 1> [... [, <Parameter N>]]])
<Result>: Variant
Value returned by the executed Python function (possibly empty).
<Module>: Character string
Name of the Python module to be loaded. See the Python documentation for more details.
Caution: The name of the module is "case-sensitive".
<Function>: Character string
Name of the Python function to be executed. This function can be found in <Module>.
Caution: The name of the function is "case-sensitive".
<Parameter 1>: Type of parameter
First parameter to be passed to the Python function.
<Parameter N>: Type of parameter
Last parameter to be passed to the Python function.
Remarks
  • The Python interpreter must have been configured beforehand (via PythonInitialize).
  • Only the following simple types can be used for the return value and for the different parameters of the Python function:
    • Boolean
    • Integer (signed or unsigned)
    • Real
    • Character string.
  • The Python module must be in the runtime directory. Otherwise, use PythonAddPath to specify the paths to be taken into account.
  • An error message is displayed in the following cases: interpreter not loaded, incorrect parameter type, etc.
  • When PythonExecute is called,
    • the strings passed as arguments are encoded in UTF-8.
    • the string returned by a function from the module in a variable of type variant is not automatically decoded. You must use UTF8ToString.

Hello Guys!

Para resolver a compilação do Python pelo Webdev voce tera que fazer o seguinte ajuste:

https://hostimage.windev.io/images/BUG64_c5a2a700bcd82b0dcceab7c195f4fad7.png

Na versao inglesa
C:\PCSOFT\WEBDEV 29\Programs\Engine

Na versão francesa
C:\PCSOFT\WEBDEV 29\Programmes\Moteur

Copiar tudo da pasta 64 e colar na pasta 32

C:\PCSOFT\WEBDEV 29\Programs\Engine\Win64x86
para
C:\PCSOFT\WEBDEV 29\Programs\Engine\Win32x86

Substituir tudo

Testar novamente o teu projeto Python vai funcionar.

Abri chamado informado do ocorrido quem sabe em futuras versoes isso esteja resolvido.

Por algum motivo o Python busca pela pasta 32 em vez de buscar pela pasta 64.

Espero ter ajudado.

PARA FUNCIONAR NO WEBDEV

É necessário setar corretamente o caminho do modulo python, para executar uma função em um módulo python:

sPythonModule is string

<IF ExecutionTarget=Windows>

sPythonModule = SysDir(srLocalAppData) + ..
[fSep]+"Programs\Python\Python39\python39.dll"

END
