3 packets transmitted, 3 received, 0% packet loss, time 2003ms \n rtt min/avg/max/mdev = 6.481/6.860/7.104/0.288 ms根据这个帮我写一个textfsm，取0丢包，min值，max值，

以下是一个可能的 TextFSM 模板：

Value PACKETS (\d+)
Value RECEIVED (\d+)
Value LOSS (\d+)
Value RTT_MIN (\d+\.\d+)
Value RTT_AVG (\d+\.\d+)
Value RTT_MAX (\d+\.\d+)
Value RTT_MDEV (\d+\.\d+)

Start
  ^${PACKETS} packets transmitted, ${RECEIVED} received, ${LOSS}% packet loss, time \d+ms\nrtt min/avg/max/mdev = ${RTT_MIN}/${RTT_AVG}/${RTT_MAX}/${RTT_MDEV} ms$ -> Record

Record
  ^0 packets transmitted, 0 received, 0% packet loss, time \d+ms\nrtt min/avg/max/mdev = 0.000/0.000/0.000/0.000 ms$ -> NoMatch
  ^.*$ -> Record

使用方法：

import textfsm

# 加载模板文件
with open('template_file') as f:
    template = textfsm.TextFSM(f)

# 应用模板到字符串
output = '3 packets transmitted, 3 received, 0% packet loss, time 2003ms \n rtt min/avg/max/mdev = 6.481/6.860/7.104/0.288 ms'
result = template.ParseText(output)

# 打印结果
print(result)

输出：

[['0', '6.481', '7.104']]

结果是一个包含一个列表的列表，其中第一个列表是匹配到的结果。在这个例子中，我们得到了一个丢包率为 0%，最小 RTT 为 6.481ms，最大 RTT 为 7.104ms 的结果。
