Greek letters in a GUI - PYTHON

Question

I don't know how to write Greek letters in a GUI. I am working on a Physics program and I need to show units on the GUI.

Do I have to download any extra libraries? Is there a module I have to use? What is the easiest way to write the letters in the GUI?

I read a lot about UTF8 but didn't figure out how to use it.

I am using Tkinter for the GUI

I am using Python 2.6.6

Thanks

Answer 1

Unicode includes definitions for both the Greek alphabet and several mathematical symbols. If you are using any form of Unicode in your environment, it should be simple:

>>> from Tkinter import *
>>> root = Tk()
>>> w = Label(root, text=u"Hello, \u03bc-world!")
>>> w.pack()
>>> root.mainloop()

This will print "Hello, μ-world!" in a Tkinter window.

Answer 2

IDLE uses Tkinter, Greek letters seem to work fine in there for me

Python 2.6.5 (r265:79063, Apr 16 2010, 13:09:56) 
[GCC 4.4.3] on linux2
Type "copyright", "credits" or "license()" for more information.

IDLE 2.6.5      
>>> print "Ω ω"
Ω ω
>>> 

If you wish to use unicode literally in your source, you should include a line like this

# -*- coding: utf-8 -*-

At the top of each file

Answer 3

>>> print( u'\u03a9' )
Ω

Works for me.
