You are not alone. debugging curses is one of the biggest obstacles to
its use.
My approach is to define a status line at the bottom of my program and
write print statements into that window. Something like:
def main(stdwin):
appwin = curses.newwin(...) # LINES-1 high
status = curses.newwin(...) # 1 line high positioned on bottom
# more code here
status.addstr(0,0, "Value of foo = %s" % foo)
curses.wrapper(main)
After debugging the status window can either be retained as an
application status bar or removed and the main window
enlarged by one line...
If anyone else has found a better way to debug curses code I'm
also keen to hear!
