将字典放入 if 语句时出现类型错误

Question

下面的代码很好（据我所知），但我认为它可能会为下半部分添加更多上下文

IncAsk = bool(True)
while IncAsk:
    try:
        Income = {'Jan': int(input("How much money did you make in January? ")),
                  'Feb': int(input("How much money did you make in February? ")),
                  'Mar': int(input("How much money did you make in March? ")),
                  'Apr': int(input("How much money did you make in April? ")),
                  'May': int(input("How much money did you make in April? ")),
                  'Jun': int(input('How much money did you make in June? ')),
                  'Jul': int(input("How much money did you make in July? ")),
                  'Aug': int(input('How much money did you make in August? ')),
                  'Sep': int(input('How much money did you make in September? ')),
                  'Oct': int(input('How much money did you make in October? ')),
                  'Nov': int(input('How much money did you make in November? ')),
                  'Dec': int(input('How much money did you make in December? '))}
    except ValueError:
        print('Oops! It seems you have made a mistake. Numbers only please. Sorry for the inconvenience.')

但这段代码的问题在于，它应该检查整个字典并查看每个个体是否为正数，如果它们都是正数，它将打印一条消息并继续。如果不是，它将重复直到用户正确为止。但是当我运行它停止并给了我一个 'type error'。上半部分运行良好，一旦达到此值就会崩溃。我已经为 if 语句尝试了多种不同的格式，所以我很确定问题更深层次，可能是上半部分的问题。

if Income(['Jan'], ['Feb'], ['Mar'], ['Apr'], ['May'], ['Jun'], ['Jul'], ['Aug'], ['Sep'], ['Oct'], ['Nov'], ['Dec']) > -1:
    print('Looks like everything is ok, now on to spending')
    IncAsk = bool(False)

Answer 1

Income不是函数，不能写成Income(...)。您使用 Income[...].

访问元素

您不能通过一次放置所有下标来测试多个字典元素。如果要测试多个元素，可以使用all()函数：

if all(val > -1 for val in Income.values()):

顺便说一句，让用户重新键入所有输入时，当他们输入错误时，这似乎是糟糕的设计。最好在输入时检查每个输入，在输入正确之前不要继续下一个输入。我建议你写一个单独的函数来获取满足所有条件的输入，并在分配给字典时调用它。
