[Tutor] curses delwin functionality?

[Bernd Prager]

Hi,

I'm trying to get my hands on some curses experiences in Python.

The examples I found don't really tell me how to get rid of subwindows and
restore the underlying window again. Is there something that replaces the
curses functionality "delwin"?
Thanks for any help!
Here's my example:

#!/usr/bin/python
import sys, curses

def sub(scrn):
s = curses.newwin(4, 30, 1, 1)
s.erase()
s.box()
s.addstr(1, 1, "sub window")
s.refresh()
s.getch()
# curses.delwin(s) <-- that doesn't exist :-/
scrn.refresh()

def main(scrn):
scrn = curses.initscr()
curses.curs_set(0)  # turn cursor off
scrn.erase()
scrn.addstr(2, 2, "press  to continue,  to quit");
while 1:
c = scrn.getch()
if c == curses.KEY_F12: sys.exit()
elif c == curses.KEY_F1: sub(scrn)

# main loop
if __name__ == '__main__':
curses.wrapper(main)
sys.exit()

I am looking for a functionality that destroys only a single subwindow
created with curses.newwin so that the underlying area can get restored
again.
curses.endwin() terminates the curses main screen, right?

Hey Matata,

>From the website  http://www.boddie.org.uk/python/HTML.html:

import urllib
# Get a file-like object for the Python Web site's home page.
f = urllib.urlopen("http://www.python.org";)
# Read from the object, storing the page's contents in 's'.
s = f.read()
f.close()


Hope this helps,
-- Bernd

[Tutor] question about mpmath product expression

[Bernd Prager]

Does anybody know if there is a precision difference when I use mpmath and
take an expression:

from mpmath import *
mp.dps = 100
mu0 = [mpf('4') * pi * power(10, -7)

rather then:

mu0 = fprod([mpf('4'), pi, power(10, -7)])

?

Thanks,
-- Bernd
