Simple Proxy Checker

Hey there, I made a simple proxy checker in Python.
Save the proxies like that in the proxylist.txt:

Code:
IP:PORT

Spoiler:Code:
import socket
import os.path
class ProxyChecker():

    def __init__(self):
        print("Starting the checker...")


    def CheckProxy(self):
        try:
            with open('proxylist.txt', 'r+') as f:
                for line in f.readlines():
                    ipAddress = str.split(line, ':')[0]
                    port = str.split(line, ':')[1]
                    proxyIP = (ipAddress, int(port))
                    s = socket.socket(family=socket.AF_INET, type=socket.SOCK_STREAM)
                    s.settimeout(5)
                    print("[!] - Checking {} ...".format(proxyIP))
                    if s.connect_ex(proxyIP):
                        pass
                    else:
                        self.AddProxy(ipAddress + ":" + str(port))
        except IOError:
            print('proxylist.txt not found')



    def AddProxy(self, proxyAddress):
        with open('positive.txt', 'a') as f:
            #Duplicate Check:
            with open('positive.txt', 'r+') as r:
                if proxyAddress in r.readlines():
                    print("[!] - {} already added!".format(proxyAddress))
                else:
                    print("[+] - {} added!".format(proxyAddress))
                    f.write(proxyAddress)


if __name__ == "__main__":
    ProxyChecker().CheckProxy()

Learn this language by myself or take courses?

Python is a very simple language and a very good place to start your coding journey. There are plenty of online resources including hackerrank.com where you can learn for free without having to install python on your pc. I do suggest you download Visual Studio Code to use as your IDE as the debugging is very good.

Hi. I like your script and thought it could do with some more functionality. It now allows users to specify input file name, output file name, verbosity, and timeout with default value of 2s. If a proxy server takes more than 2 seconds to reply it's not worth using. I also added the shebang so just run "./scriptname -h" to get the help message up (Linux only). Also, put it in /bin/ so you can just run "scriptname" from anywhere. Again, Linux only.

Code:
#! /usr/bin/python3

import socket
import os.path
import argparse as arg

class ProxyChecker():

    def __init__(self):
        print("Starting the checker...")


    def CheckProxy(self, file, timeout, verbose, output):
        try:
            with open(file, 'r') as f:
                for line in f.readlines():
                    ipAddress = str.split(line, ':')[0]
                    port = str.split(line, ':')[1]
                    proxyIP = (ipAddress, int(port))
                    s = socket.socket(family=socket.AF_INET, type=socket.SOCK_STREAM)
                    s.settimeout(timeout)
                    if verbose:
                        print("[!] - Checking {} ...".format(proxyIP))
                    if s.connect_ex(proxyIP):
                        pass
                    else:
                        self.AddProxy(ipAddress + ":" + str(port), verbose, output)
        except IOError:
            print(file + ' not found')



    def AddProxy(self, proxyAddress, verbose, output):
        with open(output, 'a') as f:
            #Duplicate Check:
            with open(output, 'r+') as r:
                if proxyAddress in r.readlines():
                    if verbose:
                        print("[!] - {} already added!".format(proxyAddress))
                else:
                    if verbose:
                        print("[+] - {} added!".format(proxyAddress))
                    f.write(proxyAddress)


def main():
    parser = arg.ArgumentParser()
    parser.add_argument("--file", "-f", type=str, required=True,
                help="File to check.")
    parser.add_argument("--timeout", "-t", type=int, default=2,
                help="Integer time out value, default value is 2 seconds.")
    parser.add_argument("--output", "-o", default="positive.txt",
                help="Output filename, default is 'positive.txt'")
    parser.add_argument("--verbose", "-v", default=False, action="store_true",
                help="Print proxies as they are checked and added.")
    args = parser.parse_args()
    file = args.file
    timeout = args.timeout
    verbose = args.verbose
    output  = args.output
    ProxyChecker().CheckProxy(file, timeout, verbose, output)
    print("Done!")

    main()
