Accessing varying command line arguements

[snippsat]

Could do it like this,so with super() inherit all the methods and properties from its parent.
Then add another parameter in the __init__() function.
I guess also popejose way could work.

import re
import sys

import bs4 as bs4

inputURL = sys.argv[1]
inputConfig = sys.argv[2]
version = sys.argv[3]
print(len(sys.argv))
if len(sys.argv) > 4:
    typeOfTest = sys.argv[4]

class Client:
    def __init__(self, URL, Config, Version):
        self.Url = URL
        self.config = Config
        self.version = Version

    def perform_test(self):
        # subprocess.call(['java','-version'])
        if len(sys.argv) > 4:
            subprocess.call(
                ['java', '-jar', 'XXX.jar', '-url', self.Url, '-config', self.config, '-specVersion',
                 self.version])
        else:
            subprocess.call(
                ['java', '-jar', 'XXX.jar', '-url', self.Url, '-config', self.config, '-specVersion',
                 self.version, '-test', self.testType])

    def read_results(self):
        pass

class TestClient(Client):
    def __init__(self, URL, Config, Version, TestType):
        super().__init__(URL, Config, Version)
        self.testType = TestType

if __name__ == "__main__":
    if len(sys.argv) > 4:
        client = Client(inputURL, inputConfig, version)
    else:
        client = TestClient(inputURL, inputConfig, version, typeOfTest)
        client.perform_test()
        client.read_results()
