您可以使用返回"字符\r
返回到行首.在 Python 2.x 中,您必须使用 sys.stdout.write
和 sys.stdout.flush
而不是 print

You can use the "return"-character \r
to return to the beginning of the line. In Python 2.x, you'll have to use sys.stdout.write
and sys.stdout.flush
instead of print
.
import time, sys
while True:
sys.stdout.write("\r" + time.ctime())
sys.stdout.flush()
time.sleep(1)
在 Python 3.3 中,您可以使用 print
函数,带有 end
和 flush
参数:
In Python 3.3, you can use the print
function, with end
and flush
parameters:
print(time.ctime(), end="\r", flush=True)
但是请注意,这种方式只能替换屏幕上的最后一行.如果您想在更复杂的仅限控制台的 UI 中使用实时"时钟,您应该查看 诅咒
.
Note, however, that this way you can only replace the last line on the screen. If you want to have a "live" clock in a more complex console-only UI, you should check out curses
.
import time, curses
scr = curses.initscr()
scr.addstr(0, 0, "Current Time:")
scr.addstr(2, 0, "Hello World!")
while True:
scr.addstr(0, 20, time.ctime())
scr.refresh()
time.sleep(1)
