sorted = sorted(fine, key=lambda x: x.FinancialStatements.BalanceSheet.TotalDebt.ThreeMonths / x.FinancialStatements.BalanceSheet.TotalCapitalization.ThreeMonths, reverse = False)

Probably because you are naming your variable sorted which shadows the sorted function. Try changing the variable name to something else and see if it improves
