Tkinter uses a lot of memory?!

[ServantOfTheSecretFire]

Hi there,

I wrote my first Python program this weekend, Conway's Game of Life,
and I used Tkinter for the graphics. I thought I had done something
wrong when I saw the memory consumption, so I wrote the simplest Tk
program I could, and yep, it takes about 40MB of memory! I'm using Red
Hat Linux 9.0 and recent versions of the software. Please look at the
output below, and tell me if I am confused...

~/python: cat /etc/redhat-release
Red Hat Linux release 9 (Shrike)

~/python: rpmquery python
python-2.2.2-26

~/python: rpmquery tk
tk-8.3.5-88

~/python: rpmquery tkinter
tkinter-2.2.2-26

~/python: cat hello.py
#!/usr/bin/python
import Tkinter as Tk
root = Tk.Tk()
Tk.Button(text= 'Quit', command=root.qu it).pack()
root.mainloop()

~/python: python hello.py &
[1] 25633

~/python: ps u

Can't say about linux, but on windows your program takes about 5.5MB.

I suppose all can suggest is that you do a lsof | grep sjm and spent
some time working out what shared libraries have been pulled in.
