    给定一个数组

    1. list = [100,80,80,30,50]

    使用代码,输入对应的序号。

    1. [4,3,3,1,2]
    1. nums = [100,80,80,30,50]
    2. # 使用集合的特性 去重
    3. nums_set = set(nums)
    4. # 转换为列表
    5. nu = list(nums_set)
    6. # 针对列表进行排序
    7. nu.sort()
    8. print(nu) # [30, 50, 80, 100]
    10. # 将list 中数据 转换为字典，
    11. nums_dict = {}
    12. count = 1
    13. for n in nu:
    14.     nums_dict[n] = count
    15.     count+=1
    16. print(nums_dict) # {30: 1, 50: 2, 80: 3, 100: 4}
    17. orders = []
    18. for num in nums:
    19.     # 通过字典的方式获取每个字段对应的值
    20.     print(nums_dict.get(num))
    21.     orders.append(nums_dict.get(num))
    22. # 最终通过字典字段映射对应的序号
    23. print(orders) #  [4, 3, 3, 1, 2]
