如何根据用户输入更新字典并使用 python 根据值排序？

Question

我下面有字典

{0: {'STATE': 'AL', 'POPULATION': '151449859682', 'TOP_CITY': '1', 'RANK': '1'}, 1: {'STATE': 'NY', 'POPULATION': '8955557', 'TOP_CITY': '6', 'RANK': '2'}, 2: {'STATE': 'CA', 'POPULATION': '7123215', 'TOP_CITY': '10', 'RANK': '3'}, 3: {'STATE': 'PH', 'POPULATION': '68557813', 'TOP_CITY': '11', 'RANK': '4'}, 4: {'STATE': 'IN', 'POPULATION': '7678676', 'TOP_CITY': '14', 'RANK': '5'}}

我想通过询问用户输入来根据 RANK 降序排序

value2sort= input('Enter the value to sort')

RANK

parameter= input('asc for ascending order and desc for descending order')

desc

预期结果低于

{4: {'STATE': 'IN', 'POPULATION': '7678676', 'TOP_CITY': '14', 'RANK': '5'}, 3: {'STATE': 'PH', 'POPULATION': '68557813', 'TOP_CITY': '11', 'RANK': '4'}, 2: {'STATE': 'CA', 'POPULATION': '7123215', 'TOP_CITY': '10', 'RANK': '3'}, 1: {'STATE': 'NY', 'POPULATION': '8955557', 'TOP_CITY': '6', 'RANK': '2'}, 0: {'STATE': 'AL', 'POPULATION': '151449859682', 'TOP_CITY': '1', 'RANK': '1'}}

Answer 1

将 sorted 与 dict() 构造函数一起使用，然后将输入的值传递给排序，您可以设置一个字典，它可以传递 True/False 的参数来处理 asc/desc

value = input('Enter the value to sort: ')
param = input('Enter "asc" for ascending and "desc" for descending order: ')
order = {'asc': False, 'desc': True}

d = dict(sorted(d.items(), key=lambda x: int(x[1][value]), reverse=order[param]))
print(d)

Enter the value to sort: RANK
Enter "asc" for ascending and "desc" for descending order: desc
{4: {'STATE': 'IN', 'POPULATION': '7678676', 'TOP_CITY': '14', 'RANK': '5'}, 3: {'STATE': 'PH', 'POPULATION': '68557813', 'TOP_CITY': '11', 'RANK': '4'}, 2: {'STATE': 'CA', 'POPULATION': '7123215', 'TOP_CITY': '10', 'RANK': '3'}, 1: {'STATE': 'NY', 'POPULATION': '8955557', 'TOP_CITY': '6', 'RANK': '2'}, 0: {'STATE': 'AL', 'POPULATION': '151449859682', 'TOP_CITY': '1', 'RANK': '1'}}
