The Python language has been ported to two major virtual machine platforms: IronPython for Microsoft .Net and Jython for Java. To get a flavour of these implementations, here are two Hello World
scripts that open a window containing a label and a button.
IronPython Hello World Window
import clr clr.AddReference("System.Drawing") from System.Drawing import ContentAlignment, Size clr.AddReference("System.Windows.Forms") from System.Windows.Forms import Button, FlowLayoutPanel, Form, Label p = FlowLayoutPanel() p.Controls.Add(Label(Text="A label:", Size=Size(50,20), TextAlign=ContentAlignment.BottomLeft)) p.Controls.Add(Button(Text="Press Me")) f = Form(Text="Hello World", Size=Size(160,70)) f.Controls.Add(p) f.ShowDialog()
Jython Hello World Window
# Jython Hello Window from java.awt import FlowLayout from javax.swing import JButton, JFrame, JLabel f = JFrame("Hello", defaultCloseOperation=JFrame.DISPOSE_ON_CLOSE, size=(170,70), layout=FlowLayout()) f.add(JLabel("A label:")) f.add(JButton("Press Me")) f.show()
Mini Observations
- IronPython makes loading the .Net libraries explicit by using the clr module.
- Both implementations allow
setX
functions in object constructor's argument list.
