How to get the last value in a list/string using Python [closed]

Question

I am a beginner in writing Python scripts and I need help on the following:

Threads::num,47141,47146,47151,47156,47161,47166,47171,47176

How can I get and display the last value '47176'

The following is the part of the code I have written:

elif sys.argv[1] == "-c": b = sys.argv[2] with open(b) as f: for line in f: if 'Threads::num' in line: print line.strip(',').split(',')[-1] print line

The output of this code is that it displays all the values as follows Threads::num,47141,47146,47151,47156,47161,47166,47171,47176

Please do help me

thx,

sid

Answer 1

Something like this:

threads_string = "Threads::num,47141,47146,47151,47156,47161,47166,47171,47176"
split_threads_string = threads_string.split(',')
print split_threads_string[-1]

Answer 2

import sys

if sys.argv[1] == '-c':
    b = sys.argv[2]

with open(b) as f:
    for line in f:
        if line.startswith('Threads::num'):
            print line.split(',')[-1].strip()

Also I would suggest using optparse instead of sys.argv
