feed_price = s.get_current_median_history_price()['base']
feed_price= float(feed_price.split()[0])
#get steem market_price
Steem_market_price_USD= float(coinmarketcap.ticker('steem', convert='USD')[0]['price_usd'])
steemit_data_history_hour.update({str(datetime.utcnow())[:-7]:{
'steem_feed_price':reward_data[0],
