unicurses' addstr() interferes with time.sleep()

Question

The time.sleep() delay will sleep before addstr() in the script below

from unicurses import *
from time import *
stdscr = initscr()
addstr("Hello")
sleep(1)
endwin()

Is there any curses function for delays?

Answer 1

Use napms rather than sleep. It works with other python/curses bindings.

The example

from unicurses import *
from time import *
stdscr = initscr()
addstr("Hello")
sleep(1)
endwin()

looks odd, since there is no explicit refresh call in endwin. Something like this might work for you:

from unicurses import *
from time import *
stdscr = initscr()
addstr("Hello")
refresh()
napms(1000)
endwin()
