How to place buy order using $200 USDT worth of ETH?

Say I have $200 USDT on my wallet, I want to place an order to buy ETHUSDT using 100% of my $200 USDT. Is there a way I can place an order using 100% of my USDT and not how many ETH I want to buy?

This is the code that I am using.

buy_order = client.create_test_order(symbol="ETHUSDT, side=‘BUY’, type=‘MARKET’, quantity=10)

This buys 10 ETH right? But I wanted to buy $200 worth of ETH. How can I do this?
