示例1: initscr

# 或者: from _curses import start_color [as 别名]
def initscr():
import _curses, curses
# we call setupterm() here because it raises an error
# instead of calling exit() in error cases.

# This is a similar wrapper for start_color(), which adds the COLORS and
# COLOR_PAIRS variables which are only available after start_color() is
# called. 示例2: start_color
