linux - conditionally replacing number with word -

i using python script detect connected devices in local network every 2 minutes - saving output in file (i save last number of ip).

this code:

import os os.system('for ip in $(seq 1 10); ping -c 1 192.168.1.$ip>/dev/null; '           '[ $? -eq 0 ] && echo "$ip" || : ; '           'done > /home/pi/desktop/network/logs/loglocal.txt') 

the output ist example:

1 2 4 7 

my question if possible replace number 7 through word? if device 7 found programm writes "seven" not 7 in file.

thanks help!

the following script job:

# note can use `{a..b}` instead of `seq` ip in {1..10} ;    # no need execute command , check it's    # return value. can in 1 line    if ping -c 1 192.168.1.$ip > /dev/null ;       # check `7`       if [ "$ip" = "7" ] ;           echo "seven"       else if [ "$ip" = 5 ] ;           echo "five"        # ... , on        else           echo "$ip"       fi    fi done > output.txt
