How to refresh curses window correctly?

Question

while 1:
    ...
    window.addstr(0, 0, \'abcd\')
    window.refresh()
    ...

window size is full terminal size, big enough to hold

Answer 1

addstr() only prints the string you specify, it does not clear the following characters. You will have to do that yourself:

• To clear characters until the end of the line, use clrtoeol(),

• To clear characters until the end of the window, use clrtobot().
