使用 if-else 語句設計一個多層決策系統,可用於確定獎學金的資格標準。該系統應考慮多種因素,例如成績、課外活動和財務需求。
要設計一個多層決策系統來根據成績、課外活動和財務需求確定獎學金資格,您需要一種結構化的方法來評估和分配獎學金金額。以下是如何使用 if-else 語句建立決策系統的逐步細分:
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))

讓我們回顧一下所提出的解決方案並分析其選擇的原因以及潛在的缺陷:
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))
結構化方法:此解決方案採用多層決策流程,有系統地評估財務狀況、課外活動和成績。這種結構化方法可以採用清晰、有組織的方法來確定獎學金資格。
詳細評估:此解決方案涵蓋了一系列具有特定閾值的條件,包括經濟需求、課外活動和學業成績,為分配獎學金金額提供了詳細的框架。
模組化:透過分離不同層級的財務需求並評估這些層級內的其他標準,該解決方案引入了更易於管理和更新的模組化結構。
清晰的決策路徑:嵌套的 if-else 語句創建了清晰的決策路徑,明確了哪些條件導致了哪些獎學金金額。
冗餘和複雜性:程式碼包含大量冗餘。例如,對成績和課外活動的檢查會重複多次。這種冗餘增加了程式碼的複雜性,並使其更難以維護和理解。
程式碼重複:每個financial_cond範圍的決策邏輯都有相似的模式,但閾值略有不同。透過整合通用邏輯並減少重複的程式碼區塊可以避免這種重複。
硬編碼值:獎學金金額和閾值是硬編碼的,這使得它不靈活。如果需要更改標準或金額,則必須手動更新代碼。使用設定檔或常數可以提高靈活性。
缺乏輸入驗證:程式碼不會驗證輸入以確保它們在預期的範圍或類型內。例如,financial_cond、extra_act 和 Grades 預計介於 1 到 100 之間,但程式碼不會強制執行或驗證這一點。
邊緣情況:此解決方案無法穩健地處理邊緣情況。例如,如果 Financial_cond、extra_act 或 Grades 正好位於邊界值上(例如,剛好 40、60 或 80),則處理有些不明確。更清晰地處理邊界情況將使決策邏輯更精確。
沒有回饋或解釋:此解決方案僅提供獎學金金額,並沒有解釋為什麼給予一定金額。新增回饋或解釋可以提高使用者的理解和透明度。
您能根據現代標準改進建議的解決方案嗎? [提示:重構冗餘、實現輸入驗證、使用常數並增強使用者回饋]
