Subject: self-modification

I'm a newbie to Python. I wanted to write a graphical interface which
would show the built-in documentation (I mean dir() and __doc__ ) of
Python. The code shows how far I got before realizing that I had to use
some self-modification feature (converting a string to a function or to
an object; i'm not sure you would call it self-modification in an
interpreted language).
I was googling around, and searching in the maillist archives and found
this:

Unanswered for two years. Not too promising :)
P.S.: I'm new to this mailing list, so I don't know whether it is
allowed to send code as attachment. (I didn't found anything about your
policy in the subscription site. ) If not, I'm sorry.

if buttonpressed == 1 :
#if the mousebutton is pressed and moved, circles should appear, but they do not
can.create_oval(event.x-r, event.y-r, event.x+r, event.y+r, fill="orange")
lab.config(text='buttonpressed=' + str(buttonpressed) )

root.geometry('600x500+200+200')
# both labels are used to check the status of the variable buttonpressed
lab = Label(root, text='cucc')
lab2 = Label(root, text='cucc2')
can = Canvas(root, width='500', height='400', bg='white')
can.bind("<Motion>",handler)

lab.pack()
lab2.pack()
can.pack()
root.mainloop()
