Using Python for .NET the clr python module - part 001 .

Python for .NET is available as a source release and as a Windows installer for various versions of Python and the common language runtime from the Python for the .NET website.
Let's install it under Windows 10.

Now I will show you how to use form and buttons.
First, you need to run the python code into python script files.
The first example is simple:
import clr

clr.AddReference("System.Windows.Forms")

from System.Windows.Forms import Application, Form

class IForm(Form):

    def __init__(self):
        self.Text = 'Simple'
        self.Width = 640
        self.Height = 480
        self.CenterToScreen()

Application.Run(IForm())
The next example comes with one button and tooltips for form and button:
import clr

clr.AddReference("System.Windows.Forms")
clr.AddReference("System.Drawing")

from System.Windows.Forms import Application, Form
from System.Windows.Forms import Button, ToolTip
from System.Drawing import Point, Size

class IForm(Form):

    def __init__(self):
        self.Text = 'Tooltips'
        self.CenterToScreen()
        self.Size = Size(640, 480)

        tooltip = ToolTip()
        tooltip.SetToolTip(self, "This is a Form")

        button = Button()
        button.Parent = self
        button.Text = "Button"
        button.Location = Point(50, 70)

        tooltip.SetToolTip(button, "This is a Button")


Application.Run(IForm())
This is the result of this python script.

Another example is how to see the interfaces that are part of a .NET assembly:
>>> import System.Collections
>>> interfaces = [entry for entry in dir(System.Collections)
... if entry.startswith('I')]
>>> for entry in interfaces:
...   print entry
...
