Sebuah sesi IDLE pendek saya malam ini:

Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.

    Personal firewall software may warn about the connection IDLE
    makes to its subprocess using this computer's internal loopback
    interface.  This connection is not visible on any external
    interface and no data is sent to or received from the Internet.
IDLE 1.2.1      
>>> f = lambda x: isinstance(x, dict) and x.keys()[0]+f(x.values()[0]) or x
>>> print f({"Selamat Idul Fitri 1428H,n":
	    {"Mohon Maaf":" Lahir dan Batin"}})
Selamat Idul Fitri 1428H,
Mohon Maaf Lahir dan Batin
