更新变量而不打印新行

Question

我正在运行这个程序，让我知道这个ip地址是关闭还是上升。我的问题是，它经常打印新的行，我希望它只显示1行，每次它更新，所以如果它在同一条线上运行，它就会从在线到离线在同一条线上运行。我该怎么做？

import os

ip = "192.168.2.1"

class bcolors:
    HEADER = '\033[95m'
    OKBLUE = '\033[94m'
    OKGREEN = '\033[92m'
    WARNING = '\033[93m'
    FAIL = '\033[91m'
    ENDC = '\033[0m'
    BOLD = '\033[1m'
    UNDERLINE = '\033[4m'

while True:

    exit_code = os.system("ping -n 1 -w 1 " + ip + " > nul") # Windows

    if exit_code == 0:
        print("status " + bcolors.OKGREEN + "ONLINE " + bcolors.ENDC)

    else:
        print("status " + bcolors.FAIL + "OFFLINE" + bcolors.ENDC)

我得到的是：

status ONLINE

Answer 1

向要打印的end参数添加回车。我觉得这应该行。

print("status " + bcolors.OKGREEN + "ONLINE " + bcolors.ENDC, end='\r')

Answer 2

可以使用end并返回回车\r。

for i in range(10):
    print(i)
    print("same line \r",end='')

输出

0
