What is the reason for that?

您需要调用curses.noecho()作为初始化的一部分。Is there a way to move the curse to the next line?

stdscr.move(y,x)将移动到绝对位置。stdscr.getyx()将告诉您当前位置。If I want to do certain things (execute some function or something) on enter key press, then what will come in ‘if’condition? e.g.

你会认为你可以调用getch()，并将结果与KEY_ENTER进行比较。实际上，你需要检查更多的值。根据终端设置、使用的库和月相，可能需要检查换行符(也称为\n、^J、ASCII 10)或回车符(\r、^M、ASCII 13)。c = stdscr.getch()

if c == curses.KEY_ENTER or c == 10 or c == 13:

# I hit ENTER

示例程序：import curses

stdscr.move((y+1) % maxy, x)

stdscr.refresh()

finally:

curses.nocbreak()

stdscr.keypad(0)

curses.echo()

curses.endwin()
