Sorry, it’s me again.
Let's learn more about "b" which means backspace. It will move one space to the left and delete the actual characters on that space. For details, please refer to the ascii encoding table

There are only two ways

1) Whole row coverage.

pythonimport sys, time

def interface_show(**kwargs):
    lineTmpla = ' '*5 + kwargs['title'] + kwargs['artist'] + kwargs['rate'] + " %-3s"
    print time_remain(lineTmpla, kwargs['minutes']),

def time_remain(lineTmpla, mins):
    count = 0 
    while (count < mins):
        count += 1
        n = mins - count
        time.sleep(1)
        sys.stdout.write("\r" + lineTmpla %(n),)
        sys.stdout.flush()
        if not n:
            return 'completed'

interface_show(title="倒计时demo", artist="哗嚓啊", rate="揍起来", minutes=5)

2) Partial coverage

You need to move the cursor. I only know b for now. If anyone knows the others and is willing to tell me, I would be very grateful

pythonimport sys, time

def interface_show(**kwargs):
    print ' '*5, kwargs['title'], kwargs['artist'], kwargs['rate'], time_remain(kwargs['minutes'])

def time_remain(mins):
    count = 0
    length = len(str(mins))
    sys.stdout.write(" " * length,)
    while (count < mins):
        count += 1
        n = mins - count
        time.sleep(1)
        sys.stdout.write(('\b' * length) + str(n),)
        sys.stdout.flush()
        if not n:
            return 'completed'

interface_show(title="倒计时demo", artist="哗嚓啊", rate="揍起来", minutes=5)
