To install the Pandas library in Delphi, you need to follow these steps:

  1. Firstly, make sure that you have installed the Python environment. You can download the latest version of Python from the official website (https://www.python.org/downloads/) and follow the installation guide.
  2. Open Delphi and open your project.
  3. Make sure you have added a TButton (button) component in your project.
  4. Add the following code in the OnClick event handler for the button.
procedure TForm1.Button1Click(Sender: TObject);
var
  PythonEngine: Variant;
  PandasModule: Variant;
begin
  try
    PythonEngine := CreateOleObject('Python.Engine');
    PandasModule := PythonEngine.ImportModule('pandas');

    // 可以使用Pandas库进行数据处理等操作
    // 例如：
    // PandasModule.read_csv('data.csv');

    ShowMessage('Pandas库已成功导入');
  except
    on E: Exception do
      ShowMessage('无法导入Pandas库: ' + E.Message);
  end;
end;
  1. Run your project and click on the button. If everything is okay, you will see a message box displaying “Pandas library has been successfully imported”.

Please note that this method creates a Python interpreter with OLE objects in Delphi and imports the Pandas module. You can then use the functions and methods in the Pandas module for data processing and analysis.

I hope this can help you install the Pandas library and use it in Delphi.
