Sort part datframe decreasing and an another part increasing
I don't really know the easy way out but you could use this until someone point it out.
df_desc=self.orderbook_agreg_btc[["bids_qty","bids_price","exchange_name_bid"]].sort_values(["bids_price"],ascending= False)
df_asc=self.orderbook_agreg_btc[["asks_qty","asks_price","exchange_name_ask"]].sort_values(["asks_price"],ascending= True)
df = df_desc.append(df_asc)
In a data frame with 6 column a,b,c,d,e,f
i want to sort a,b,c by a (ascending) and d,e,f by f (descending)
