Hello not a bug, but however a question from a newbie in dex swapping.

There on line 1011:
[input_token, self.get_weth_address(), output_token],

why are the default for v2 a 3 way path, I debugged the code yesterday, because I already had some WETH in my meta account, so naturally I set the input to weth, and output to what I wanted to swap i for, which kept failing with "SAME ADDRESS" error.

Are there any perks of using a 3-way route over a 2-way route on Uniswap V2, in my own clumsy and logic (VERY new to defi) it should be faster and cheaper with a 2-way router rather than a 3-way route, right?

Can someone explain the implementation reason to me, as I cant find it in the documentation and neither that it defaults to weth as middle route, perhaps i just used it wrong.... but it would be great to get some perspective on the matter

uniswap=Uniswap(address=address,default_slippage=0.5,private_key=private_key,version=version,provider=provider)web3=Web3(Web3.HTTPProvider(mainnet_url))token_meta=uniswap.get_token(token,'erc20')spend_eth='0.001'spend=web3.to_wei(spend_eth,'ether')Amount=uniswap.get_price_input(WETH_PAIR_ADDRESS,token,spend)uniswap.make_trade(WETH_PAIR_ADDRESS,token,spend,fee_on_transfer=True)
