Python 2.7 passing variables from functions

[zetto33]

Hi, this is my first thread. I am beginning with Python, and I did not fully understand how can I transfer variables in between classes, nor outside classes.
I am using python-2.7.17.amd64 on a Windows 2012 R2.
My intention is to perform a basic check on some Cisco appliances.
In order to do the same I am using paramiko.

Below code display the results as expected, occurs that my intention is to store the results in strings (outside class), but I am not able to make it works.

    def runAccess(self):
        #Access the system
        remote_conn_pre = self.paramiko.SSHClient()
        remote_conn_pre
        remote_conn_pre.set_missing_host_key_policy(self.paramiko.AutoAddPolicy())
(...)
        remote_conn = remote_conn_pre.invoke_shell()
(...)
        self.remote_conn = remote_conn
        return self.remote_conn
        
    def runFilter(self):
        runcommand = self.runAccess()
        remote_conn = self.remote_conn

For example, I need to pass string remote_conn to Function def runFilter(self), but instead of doing it, I am calling it via runcommand = self.runAccess() inside runFilter(self).

My intention was to call def runAccess only once, store def runFilter outside Class/Function, then call runAccess multiple times (pulling data either from a DB, or txt file)

This is the entire code

#
!/usr/bin/env python

import paramiko
import time
import os
import re

sshUsername = "admin"                #sshUsername = sshuser
sshPassword = "password1234"             #sshPassword = sshpasw
sshIP = "192.168.1.201"              #sshIP = sship
sshHost = sshIP                      #sshHost = sshhost
CommandToApply = "utils ntp status"  #CommandToApply = comtoap
WaitTimeAfterCommand = 5             # WaitTimeAfterCommand = waitcom
KeyWordToFilter = "unsynchronised"   #KeyWordToFilter = keywflt
GetHowManyWordsAfterKeyword = 2      # GetHowManyWordsAfterKeyword = getword
commout = ""


#Classes
class Runcommands: 
    def __init__(self, keywflt, getword, commout, sship, sshhost, sshuser, sshpasw, comtoap, waitcom, paramiko):
        self.keywflt = keywflt
        self.getword = getword
        self.output = commout
        self.ntpoutput = ""
        self.sshIP = sship
        self.sshHost = sshhost
        self.sshUsername = sshuser
        self.sshPassword = sshpasw
        self.CommandToApply = comtoap
        self.WaitTimeAfterCommand = waitcom
        self.paramiko = paramiko
        
    def runAccess(self):
        #Access the system
        remote_conn_pre = self.paramiko.SSHClient()
        remote_conn_pre
        remote_conn_pre.set_missing_host_key_policy(self.paramiko.AutoAddPolicy())
        remote_conn_pre.connect(self.sshIP, username=self.sshUsername, password=self.sshPassword, look_for_keys=False, allow_agent=False)
        print("SSH connection established to " + self.sshHost)
        remote_conn = remote_conn_pre.invoke_shell()
        print("Interactive SSH session established")
        output = remote_conn.recv(1000)
        #Waiting time to login into system
        time.sleep(10)
        self.remote_conn = remote_conn
        return self.remote_conn
        
    def runFilter(self):
        runcommand = self.runAccess()
        remote_conn = self.remote_conn
        #Apply Commands into System
        remote_conn.send("\n")
        remote_conn.send(self.CommandToApply + "\n")
        time.sleep(self.WaitTimeAfterCommand)
        output = remote_conn.recv(5000)
        if self.keywflt in output:
            count = 0
            ntp = re.search(self.keywflt, output)
            keywordstart = ntp.start()
            keywordend = ntp.end()
            keywordend = keywordend + self.getword
            for x in output:
                count = count + 1
                if count > keywordstart and count <= keywordend:
                    self.ntpoutput = self.ntpoutput + x
            ntpoutput = self.ntpoutput
            return(ntpoutput)
        else:
            print("Could not read output from previous comand: " + output)
        #remote_conn.close()

resultado2 = Runcommands(KeyWordToFilter, GetHowManyWordsAfterKeyword, commout, sshIP, sshHost, sshUsername, sshPassword, CommandToApply, WaitTimeAfterCommand, paramiko).runFilter()
print(resultado2)

Results are display as expected, but code still not doing what I need. Meanwhile I try to store only the strings I have different errors, but mostly the same is not passing.

C:\Users\Administrator\Desktop\Script>python ssh5.py
SSH connection established to 192.168.1.201
Interactive SSH session established
unsynchronised

I appretiate any help

Thank you

python 2.7 is no longer supported you should consider upgrading to 3.8.1 (the current version).
