IPythonList.Item

Syntax

Item(Index: Integer): Variant;

Parameters

Index. List element index.

Description

The Item property returns value of list element with the specified index.

Example

Executing the example requires a folder with Pythons modules: D:\Work\Python\. The folder contains the sample.en module. The following function is implemented in the module:

import random
def getNewList(count):
res = []
i = 0
while i < count:
res.append(random.uniform(0, 100))
i = i + 1
return res

Add a link to the Python system assembly.

Sub UserProc;
Var
    pUtils: IPythonUtils;
    pList: IPythonList;
    Result, v: Variant;
    Arr: Array;
Begin
    pUtils := New PythonUtils.Create;
    pUtils.AddFolderToPythonPath("d:\Work\Python\");
    //Get a list which is a result of the function execution
    Result := pUtils.Invoke("sample", "getNewList", 10);
    //Create a list from obtained result of the getNewList function
    pList := New PythonList.Create(Result);
    //As the getNewList function result is an object, the list created in pList
    //will contain one element. This element must be cast to the IPythonList type, in order
    //to work with separate elements from the list from the getNewList result
    pList := pList.Item(0) As IPythonList;
    Debug.WriteLine(pList.Length);
    Arr := pList.ToArray;
    For Each v In Arr Do
        Debug.Write(v + ", ");
    End For;
End Sub UserProc;

On executing the example the getNewList Python function is executed. This function returns a list with random numbers. The obtained list will be transformed into a Fore array. Values of array elements are displayed in the development environment console.
