can we use regular expression in split or strip function??

i have a file as below

abc started on port 3458
status abc 255.255.255.345:5679 closed

i need to strip or split the above file wherever there are numericals in it ,as the port number keeps changing on running the scripts and it has to be compared with a sample file each time

is there any better way to achieve the same ??

You only want the port number? Maybe one of the following will work for you.

lineList = ['abc started on port 3458', 'status abc 255.255.255.345:5679 closed']
 
import re
 
patt = re.compile(r'port (\d+)')
for item in lineList:
    m = patt.search(item)
    if m:
        print m.group(1)
 
patt = re.compile(r'([0-9]+)$')
for item in lineList:
    for word in item.split():
        m = patt.match(word)
        if m:
            print m.group(1)
 
for item in lineList:
    if 'port' in item:
        print item.split()[-1]

thanks :) ...i actually want to eliminate the port no. and have only the text either before or after the port number
