In my Flask backend, I receive a dict that gets processed and added to different dicts.
def updateIncomeExpenses(self, incomingUpdate):''' The list of dicts are iterated over, and dicts are added to their respective lists. Parameter: incomingUpdate (list): A list of dictionaries with entries that are either incomes or expenses''' self.__latestUpdate = incomingUpdate for item in self.__latestUpdate: item = {key:val for key,val in item.items() if val != None} if item.get("incomes"): item["incomes"] = float(item.get("incomes")) self.__incomes[item.get("id")] = item self.__incomes["summary"] += item.get("incomes") elif item.get("expenses"): item["expenses"] = float(item.get("expenses")) self.__expenses[item.get("id")] = item self.__expenses["summary"] += item.get("expenses") elif item.get("savings"): item["savings"] = float(item.get("savings")) self.__savings[item.get("id")] = item self.__savings["summary"] += item.get("savings") elif item.get("investments"): item["investments"] = float(item.get("investments")) self.__investments[item.get("id")] = item self.__investments["summary"] += item.get("investments")Even as I don't do any comparisons, the following error is thrown, and the traceback is not helping me find it.
Error: TypeError: '<' not supported between instances of 'int' and 'str'
