inno-setup - Inno Setup - 设置 [Files] 后使用 [Code] 中的输入作为参数

Question

我有一段脚本可以获取 Python Home 的位置。[代码]部分如下 -

; Script generated by the Inno Setup Script Wizard.
; SEE THE DOCUMENTATION FOR DETAILS ON CREATING INNO SETUP SCRIPT FILES!
#define code
#define MyAppName "API DAST"
#define MyAppVersion "0.1"
#define MyAppPublisher "Prateek Inc."
#define MyAppURL "https://prateek.com"

  InputDirWizardPage.Add('&Location of Python Home:');

  //Will this get latest value even if you go back???
  PythonHome := InputDirWizardPage.Values[0]; 
  Log('Python Home - '+PythonHome);
  AfterID := InputFileWizardPage.ID;

  OutputMsgWizardPage := CreateOutputMsgPage(AfterID, 'CreateOutputMsgPage', 'ADescription', 'AMsg');

  OutputMsgMemoWizardPage := CreateOutputMsgMemoPage(AfterID, 'CreateOutputMsgMemoPage', 'ADescription', 'ASubCaption', 'AMsg');
  AfterID := OutputMsgMemoWizardPage.ID;

  OutputProgressWizardPage := CreateOutputProgressPage('CreateOutputProgressPage', 'ADescription');
  OutputProgressWizardPageAfterID := AfterID;
end;

function NextButtonClick(CurPageID: Integer): Boolean;
var
  Position, Max: Integer;
begin
  if CurPageID = OutputProgressWizardPageAfterID then begin
    try
      Max := 25;
      for Position := 0 to Max do begin
        OutputProgressWizardPage.SetProgress(Position, Max);
        if Position = 0 then
          OutputProgressWizardPage.Show;
        Sleep(2000 div Max);
      end;
    finally
      OutputProgressWizardPage.Hide;
    end;
  end;
  Result := True;
end;

function PrepareToInstall(var NeedsRestart: Boolean): String;
begin
  if SuppressibleMsgBox('Do you want to stop Setup at the Preparing To Install wizard page?', mbConfirmation, MB_YESNO, IDNO) = IDYES then
    Result := 'Stopped by user';
end;

function GetPythonHome(Param: String): string;
begin
  Result := 'C:\Python27'; //Use default
end;

我不知道如何InputDirWizardPage.Values[0]在设置后将其作为输入来运行 Python 脚本（更改复制文件夹中的配置文件）。我该怎么做 ？

处理了 Invalid Identifier 异常。显然 Pascal 脚本与 Pascal 不同
