TypeError: buy_limit() missing 2 required positional arguments: 'quantity' and 'rate'

[tunage]

I am trying to make a buy limit purchase via the bittrex api and I am getting an error that my arguments are in the wrong place.

from bittrex.bittrex import API_V2_0, Bittrex
import json

my_bittrex = Bittrex("zzzzz", "zzzzz", api_version=API_V2_0)

trade = 'BTC'
currency = 'TRX'
market = '{0}-{1}'.format(trade, currency)

b = (my_bittrex.buy_limit({market, 100, float(0.00005550)}))

error:

Traceback (most recent call last):
File "bittrex/apitest.py", line 17, in
b = (my_bittrex.buy_limit({market, 100, float(0.00005550)}))
TypeError: buy_limit() missing 2 required positional arguments: 'quantity' and 'rate'

How do I properly position my arguments for bittrex?

I also tried:

b = (my_bittrex.trade_buy({market, 100, float(0.00005550)}))

and

b = my_bittrex.trade_buy(market=market, quantity=100, rate=float(0.00005550))

and

params = {'market': market, 'quantity': 100, 'rate': float(0.00005550)}
#b = my_bittrex.trade_buy(**params)
print (b)
