What regular expression must I do in python in re.findall() to get value of percent loss packet?
The problem is that the result written to the variable has the form one time:
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
--- 192.168.1.1 ping statistics ---
300 packets transmitted, 300 received, 0% packet loss, time 299466ms
rtt min/avg/max/mdev = 0.976/4.225/26.866/3.043 ms
and the other time:
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
--- 192.168.1.1 ping statistics ---
300 packets transmitted, 299 received, 0,333333% packet loss, time 299452ms
rtt min/avg/max/mdev = 1.231/4.878/19.140/2.807 ms
What the regular expression should look like in code?
wynik_ip_modem = os.popen("ping -c 5 -q 192.168.1.1").read()
wynik_procent = re.findall('???????',wynik_ip_modem)
to read the value of lost packets alone, whether if the ping result is a decimal or an integer?
>Solution :
\d*[\.|\,]?\d+%

The reason this works is % is only found in the packet loss part.
