Question

我正在看这个网站上的其他python代码，它们也有类似的问题，但是这些代码与我的代码有很大不同，并且看起来更加混乱，因此阅读它们并没有太大帮助。无论如何，我想看看如何让用户在他们创建的列表中添加或删除，该如何做？这段代码中的所有内容都可以正常运行，但是我只想知道我需要添加哪些内容，以便我可以让用户添加或删除项目。

temperatureList = list()

weather=int(input("Enter the amount of days that you are looking at for 
the weather:"))

print("Enter the high temperature for those next days: ")

for i in range(int(weather)):
    k=int(input(""))
    temperatureList.append(int(k))

sm=sum(temperatureList)

avg=sm/weather

print("SUM = ",sm)

print("AVERAGE = ",avg)

对于添加和删除，您可以有一个循环，不断询问用户添加和删除数字，并显示更新的统计信息例如

while True:
    action = int(input("Input -1 if you want to add to the list again. Or -2 if you want to remove from the list"))

    if action == -1:
        print("Enter what you want to be added ")
        add = int(input(""))
        temperatureList.append(add)
        print(temperatureList)
        sm = sum(temperatureList)

        avg = sm / weather

        print("SUM = ", sm)

        print("AVERAGE = ", avg)
    elif action == -2:
        if len(temperatureList) > 1:
            del temperatureList[-1]
            print(temperatureList)
            sm = sum(temperatureList)
            avg = sm / weather
            print("SUM = ", sm)
            print("AVERAGE = ", avg)
        else:
            print("Everything removed from the list")

如何让用户向列表中添加或删除新项目？
