Python 在代码执行期间最小化CMD窗口
附加我的代码片段 目标:我试图在一定的时间间隔(用户定义)对网站进行ping。如果URL有效,它将在默认浏览器中打开网页。如果没有,它将继续ping,直到用户定义的时间间隔到期 问题:代码工作完美,但符合指令要求 response=os.system(“ping”+url) 它会弹出屏幕上的cmd窗口,我需要每次最小化它。一直用手做这件事很烦人。有什么方法可以调整终端窗口的大小或使其在代码过期之前一直最小化 对操作系统的一点手动研究让我进入了操作系统。get_terminal_size(),但没什么。我还研究了其他一些可以解决这个问题但没有得到任何信息的库Python 在代码执行期间最小化CMD窗口,python,Python,附加我的代码片段 目标:我试图在一定的时间间隔(用户定义)对网站进行ping。如果URL有效,它将在默认浏览器中打开网页。如果没有,它将继续ping,直到用户定义的时间间隔到期 问题:代码工作完美,但符合指令要求 response=os.system(“ping”+url) 它会弹出屏幕上的cmd窗口,我需要每次最小化它。一直用手做这件事很烦人。有什么方法可以调整终端窗口的大小或使其在代码过期之前一直最小化 对操作系统的一点手动研究让我进入了操作系统。get_terminal_size(),但没
import os, time, webbrowser
#Enter URL that need to check. Add input()
url = "167.6.2.200"
input_time = float(input("How long ping should work: "))
current_time = time.time() #note current time
actual_time = 0
isHostOn=0
#r = (os.get_terminal_size())
response =0
#Execute the loop till the time expires entered by User
while((input_time + current_time) > actual_time):
response = os.system("ping " + url)
if response ==0:
webbrowser.open_new_tab("https://167.6.2.200:446/")
break;
else:
#add Exception if any
#print("no")
pass # do nothing
actual_time = time.time()
#time.sleep(5)
我是否有可能每次都调整/最小化打开的cmd窗口?在后台执行命令的任何更改
注:我正在使用Windows10操作系统(与Windows10一起使用)
