Python - Poloniex Push API

Question

I am trying to get Live data in Python 2.7.13 from Poloniex via the push API. I read a lot of posts (including How to connect to poloniex.com websocket api using the python library ) and I came to the following code:

from autobahn.twisted.wamp import ApplicationSession
from autobahn.twisted.wamp import ApplicationRunner
from twisted.internet.defer import inlineCallbacks
import six


class PoloniexComponent(ApplicationSession):
    def onConnect(self):
        self.join(self.config.realm)

    @inlineCallbacks
    def onJoin(self, details):
        def onTicker(*args):
            print("Ticker event received:", args)

        try:
            yield self.subscribe(onTicker, 'ticker')
        except Exception as e:
            print("Could not subscribe to topic:", e)


def main():
    runner = ApplicationRunner(six.u("wss://api.poloniex.com"), six.u("realm1"))
    runner.run(PoloniexComponent)


if __name__ == "__main__":
    main()

Now, when I run the code, it looks like it is working successfully, but I do not know where I get the data. I have two questions:

• I would really appreciate if anyone could go through the process of subscribing and receiving ticker data, which I will discuss in detail in python starting from step 0: I run the program on Spyder on Windows. Should I somehow activate Crossbar?

• ? Ctrl+c, , , : ReactorNonRestartable.

#TO SAVE THE HISTORICAL DATA (X MINUTES/HOURS) OF EVERY CRYPTOCURRENCY PAIR IN POLONIEX:

    from poloniex import Poloniex
    import pandas as pd
    from time import time
    import os

    api = Poloniex(jsonNums=float)

    #Obtains the pairs of cryptocurrencies traded in poloniex
    pairs = [pair for pair in api.returnTicker()]

    i = 0
    while i < len(pairs):
        #Available candle periods: 5min(300), 15min(900), 30min(1800), 2hr(7200), 4hr(14400), and 24hr(86400)
        raw = api.returnChartData(pairs[i], period=86400, start=time()-api.YEAR*10)
        df = pd.DataFrame(raw)

        # adjust dates format and set dates as index
        df['date'] = pd.to_datetime(df["date"], unit='s')
        df.set_index('date', inplace=True)

        # Saves the historical data of every pair in a csv file
        path=r'C:\x\y\Desktop\z\folder_name'
        df.to_csv(os.path.join(path,r'%s.csv' % pairs[i]))
