Name
getch
Synopsis
w.getch( )Returns an integer c corresponding to a
user keystroke. c between
0 and 255 represents an
ordinary character, while c greater than
255 represents a special key.
curses supplies names for special keys, so you can
test c for equality with such readable
constants as curses.KEY_HOME (the Home special
key), curses.KEY_LEFT (the left-arrow special
key), and so on. The list of all curses
special-key names (about 100 of them) is in Python’s
free documentation, specifically, in the Python
Library
Reference, Section
6.13.3
Constants, for
current versions of Python. If you have set window
w to no-delay mode by calling
w
.nodelay(True),
w
.getch raises an
exception if no keystroke is ready. By default, however,
w
.getch waits until the
user hits a key.
