我想知道为什么我会收到类型错误：类型为"int"的参数不可迭代

Question

我正试图根据值列表中的最后一个数字制作名称列表。新列表将根据最高数字到最低数字排序，但它是一个名称列表。

def generate_prioritized_list(unordered_people):
nums=[]
for i in folks:
nums.append(folks[i][6])
nums.sort(reverse=True)
for i in nums:
names=[]
for name in folks:
if i in folks[name][6]:
names.append(folks[i])
for i in names:
print(i)

print(generate_prioritized_list(folks))

我正试图获得按列表中每个人属性的最后一个值从高到低排序的名称列表。

Answer 1

我将key参数用于sorted函数

sorted(folks, key=lambda x: folks[x][-1])[::-1]

• sorted从字典中取出键
• key=lambda x: folks[x][-1]决定如何排序这些键
• [::-1]将列表反转。
