There is something wrong:
if (int(pairAddress[2:], 16) == 0):
print("Removed " + pair.name + ": no exchange")
pairsList.remove(pair)
continue
the pair generated by combinations is:
++++++++++++++++++++
DAI USDT
DAI LINK
DAI USDC
DAI WETH
DAI sUSD
USDT LINK
USDT USDC
USDT WETH
USDT sUSD
LINK USDC
LINK WETH
LINK sUSD
USDC WETH
USDC sUSD
WETH sUSD
++++++++++++++++++++

when access pair after remove operation:
say,
uniswapV2 = self.w3.eth.contract(address=pair.exchanges['Uniswap']['address'],
we get a KeyError: 'Uniswap'

Suggestion:

    if (int(pairAddress[2:], 16) == 0):
        print("Removed " + pair.name + ": no exchange")
        # pairsList.remove(pair)
        # continue
        removePair.append(pair)


    if (ABI.find("Contract source code not verified") > -1):
        print("Contract source code not verified! \n Try https://etherscan.io/address/" + pairAddress)
        # removePair.append(pair)
        continue

before return:
_list = list(set(removePair))
removePair = _list
for rePair in removePair:
pairsList.remove(rePair)

It seems to work for me
