打印字典中最小列表中的最大值

Question

我当前的字典是：

有3个键，NSW，QLD和VIC。 我想从每个列表中找到最小值，然后通过指定一个值来打印这些“最小值”中的最大值

这是一个更大问题的一部分：到目前为止，我所做的是，

rainfall_and_state = {}
is_first_line = True

for row in open("climate_data_2017.csv"):
  if is_first_line:
    is_first_line = False
  else:
    values = row.split(",")
    month = values[0].split("-")[1]
    rainfall = float(values[6])
    state = values[1]

    if state in rainfall_and_state:
      rainfall_and_state[state].append(rainfall)
    else:
      rainfall_and_state[state] = [rainfall]

我认为这部分是错误的

minimum = {}
for key in rainfall_and_state:
  rainfalls = rainfall_and_state[key]
  minimum_rainfall = min(rainfall_and_state)
  minimum[key] = minimum_rainfall

print(rainfall_and_state)

如果您希望我附上较大的问题，可以更好地解释，我可以这样做

Answer 1

每个列表的最小值

>>> l = [(k, min(v)) for k,v in d.items()] 

[('VIC', 0.0), ('QLD', 0.2), ('NSW', 0.2)]

其中最大：

>>> max(x[1] for x in l)

0.2

要获取密钥，值：

>>> max(l, key=lambda x: x[1])

('QLD', 0.2)
