使用 if-else 语句设计一个多层决策系统,可用于确定奖学金的资格标准。该系统应考虑多种因素,例如成绩、课外活动和财务需求。
要设计一个多层决策系统来根据成绩、课外活动和财务需求确定奖学金资格,您需要一种结构化的方法来评估和分配奖学金金额。以下是如何使用 if-else 语句创建决策系统的逐步细分:
def scholarship(financial_cond, extra_act, grades): if financial_cond >=80: if extra_act >=80: if grades >=80: return 5000 if grades>= 60 and grades <80: return 3000 if grades>= 40 and grades <60: return 2000 if extra_act >= 60 and extra_act < 80: if grades >=80: return 4000 if grades>= 60 and grades <80: return 2000 if grades>= 40 and grades <60: return 1000 if extra_act >= 40 and extra_act <60: if grades >=80: return 3000 if grades>= 60 and grades <80: return 1000 if grades>= 40 and grades <60: return 000 if financial_cond >=60 and financial_cond <80: if extra_act >=80: if grades >=80: return 4000 if grades>= 60 and grades <80: return 2000 if grades>= 40 and grades <60: return 1000 if extra_act >= 60 and extra_act < 80: if grades >=80: return 3000 if grades>= 60 and grades <80: return 1000 if grades>= 40 and grades <60: return 0000 if extra_act >= 40 and extra_act <60: if grades >=80: return 2000 if grades>= 60 and grades <80: return 0000 if grades>= 40 and grades <60: return 000 if financial_cond >= 40 and financial_cond <60: if extra_act >=80: if grades >=80: return 3000 if grades>= 60 and grades <80: return 1000 if grades>= 40 and grades <60: return 000 if extra_act >= 60 and extra_act < 80: if grades >=80: return 2000 if grades>= 60 and grades <80: return 000 if grades>= 40 and grades <60: return 000 if extra_act >= 40 and extra_act <60: if grades >=80: return 1000 if grades>= 60 and grades <80: return 000 if grades>= 40 and grades <60: return 000 else: return 0 financial_cond = float(input('enter financial condition in 1 to 100 ')) extrac_act = float(input('enter the extracurricular participation in 1 to 100 ')) grades= float(input('enter the grades of the student ')) print(scholarship(financial_cond, extrac_act, grades))

让我们回顾一下所提出的解决方案并分析其选择的原因以及潜在的缺陷:
def scholarship(financial_cond, extra_act, grades): if financial_cond >=80: if extra_act >=80: if grades >=80: return 5000 elif grades >= 60: return 3000 elif grades >= 40: return 2000 elif extra_act >= 60: if grades >=80: return 4000 elif grades >= 60: return 2000 elif grades >= 40: return 1000 elif extra_act >= 40: if grades >=80: return 3000 elif grades >= 60: return 1000 elif grades >= 40: return 0 elif financial_cond >=60: if extra_act >=80: if grades >=80: return 4000 elif grades >= 60: return 2000 elif grades >= 40: return 1000 elif extra_act >= 60: if grades >=80: return 3000 elif grades >= 60: return 1000 elif grades >= 40: return 0 elif extra_act >= 40: if grades >=80: return 2000 elif grades >= 60: return 0 elif grades >= 40: return 0 elif financial_cond >= 40: if extra_act >=80: if grades >=80: return 3000 elif grades >= 60: return 1000 elif grades >= 40: return 0 elif extra_act >= 60: if grades >=80: return 2000 elif grades >= 60: return 0 elif grades >= 40: return 0 elif extra_act >= 40: if grades >=80: return 1000 elif grades >= 60: return 0 elif grades >= 40: return 0 else: return 0 financial_cond = float(input('Enter financial condition in 1 to 100 ')) extra_act = float(input('Enter the extracurricular participation in 1 to 100 ')) grades = float(input('Enter the grades of the student ')) print(scholarship(financial_cond, extra_act, grades))
结构化方法:该解决方案采用多层决策流程,系统地评估财务状况、课外活动和成绩。这种结构化方法可以采用清晰、有组织的方法来确定奖学金资格。
详细评估:该解决方案涵盖了一系列具有特定阈值的条件,包括经济需求、课外活动和学业成绩,为分配奖学金金额提供了详细的框架。
模块化:通过分离不同级别的财务需求并评估这些级别内的其他标准,该解决方案引入了更易于管理和更新的模块化结构。
清晰的决策路径:嵌套的 if-else 语句创建了清晰的决策路径,明确了哪些条件导致了哪些奖学金金额。
冗余和复杂性:代码包含大量冗余。例如,对成绩和课外活动的检查会重复多次。这种冗余增加了代码的复杂性,并使其更难以维护和理解。
代码重复:每个范围的financial_cond的决策逻辑都有相似的模式,但阈值略有不同。可以通过整合通用逻辑并减少重复的代码块来避免这种重复。
硬编码值:奖学金金额和阈值是硬编码的,这使得它不灵活。如果需要更改标准或金额,则必须手动更新代码。使用配置文件或常量可以提高灵活性。
缺乏输入验证:代码不会验证输入以确保它们在预期的范围或类型内。例如,financial_cond、extra_act 和grades 预计在 1 到 100 之间,但代码不会强制或验证这一点。
边缘情况:该解决方案不能稳健地处理边缘情况。例如,如果 financial_cond、extra_act 或 grades 正好位于边界值上(例如,正好 40、60 或 80),则处理有些不明确。更清晰地处理边界情况将使决策逻辑更精确。
没有反馈或解释:该解决方案仅提供奖学金金额,并没有解释为什么给予一定金额。添加反馈或解释可以提高用户理解和透明度。
