Stored procedures
Specifies the location of the Python DLL to be loaded.
Example
sPythonModule is string
<IF ExecutionTarget=Windows>
sPythonModule = SysDir(srLocalAppData) + ..
[fSep]+"Programs\Python\Python39\python39.dll"
<ELSE>
<IF ExecutionTarget=Linux>
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> = PythonInitialize(<DLLLocation>)
<Result>: Boolean
  • True if loaded successfully,
  • False otherwise.
<DLLLocation>: Character string
Full or relative path of the Python DLL to be loaded.
Remarks
  • The Python DLL must be the same architecture as the application. For example, if the application is executed in 32-bit mode, a 32-bit DLL must be used.
  • The version of the DLL is important: The Python ABI may change from one version of Python to the other (see the Python documentation). A Python interface compatible with Python 3.9 must be used.
  • Error management:
    If there is a problem during loading, a fatal error is thrown: version not supported, internal Python error, etc.
