How to load poloniex market data CCXT

ccxt.py

import ccxt

# Load the poloniex exhange. There is
# limited functionality available with the
# public API where you don't need to key e.g
# we can query the exchanges's state. We
# can't place trades without setting up a key
# and passing this to ccxt.
poloniex = ccxt.poloniex()
poloniex.load_markets()

# poloniex.markets is just a massive
# dictionary, so we could access all of the
# keys via poloniex.markets.keys() to see
# all of the available markets in poloniex.
# Alternatively you could just print out
# poloniex.markets, but be warned there is a
# lot of data!
print(poloniex.markets['ETC/BTC'])
