【OMP】問卷 ### 綜合演練 選擇題1-10 #### 1. 以open(filename[,mode][,encode]) 開啟檔案，下列何者是 mode 參數預設的模式? ( A ) 讀取模式 ( B ) 寫入模式 ( C ) 附加模式 ( D ) 以上皆是 答: ( A ) 讀取模式 #### 2. Python 提供何種內建函式，可以開啟指定的檔案，以便進行檔案內容的讀取、寫入或修改？ ( A ) file() ( B ) input() ( C ) open() ( D ) output() 答: ( C ) open() #### 3. 下列何函式可以讀取一列字元？ ( A ) readable() ( B ) read() ( C ) readlines() ( D ) get(ch) 答: ( B ) read() #### 4. 下列程式建立的檔案物件，可以執行何種動作？ f=open('file1.txt','w') f.write("Hello Python!") f.close() ( A ) 讀取 ( B ) 寫入 ( C ) 可讀取也可寫入 ( D ) 以上皆非 答: ( B ) 寫入 #### 5. 執行下列程式，下列顯示結果何者正確？ try: print(x) except: print("y") finally: print("z") ( A ) x ( B ) y ( C ) xz ( D ) yz ```python try: print(x) except: print("y") finally: print("z") ``` y z #### 6. open(filename,mode,encode) 函式的參數中，其中只有那一個參數是必填？ ( A ) filename ( B ) mode ( C ) encode ( D ) 以上皆是 答: ( A ) filename #### 7. 如果作業系統是繁體中文 Windows 系統，預設的編碼為何？ ( A ) UTF-8 ( B ) cp950 ( C ) unicode ( D ) GB2312 答: ( B ) cp950 #### 8. 下列有關 readlines() 的敘述，何者正確？ ( A ) 會讀取全部文件內容 ( B ) 以串列方式傳回 ( C ) 包括「\n」跳列字元，甚至是隱含的字元 ( D ) 以上皆是 答: ( D ) 以上皆是 #### 9. 執行下列程式，下列顯示結果何者正確？ n=1 try: print(n) except: print("變數不存在!") ( A ) 1 ( B ) n ( C ) 變數不存在 ( D ) 以上皆是 ```python n=1 try: print(n) except: print("變數不存在!") ``` 1 #### 10. 班上的除錯高手大匹，在他的程式中加入了錯誤的補捉在 try…except…finally 敘述中，無論例外有沒有發生都會執行下列那些程式區塊？ ( A ) try ( B ) except ( C ) finally ( D ) 以上皆是 答: ( C ) finally ### 教學影音 lesson 10 ```python a = 11 b = 2 try : print(a / b) except ZeroDivisionError : print("ZeroDivisionError") except : print("except") else: print("else except") finally: print("after exception...") ``` 5.5 else except after exception... ```python a = 11 b = 0 try : print(a / b) except : print("except") else: print("else except") finally: print("after exception...") ``` except after exception... ```python a = 11 b = 0 try : print(a / b) except ZeroDivisionError : print("ZeroDivisionError") except : print("except") else: print("else except") finally: print("after exception...") ``` ZeroDivisionError after exception... ## 【self practice】 try: - 嘗試執行的程式碼 - 如果發生例外，則控制權轉移到相應的 except 區塊 except ExceptionType1 as e1: - 處理 ExceptionType1 類型的例外 except ExceptionType2 as e2: - 處理 ExceptionType2 類型的例外 else: - 如果在 try 區塊中沒有發生例外，則執行這裡的程式碼 finally: - 無論是否發生例外，都會執行這裡的程式碼 ```python try: x = 10 / 0 except ZeroDivisionError as e: print(f"Error: {e}") else: print("No exception occurred.") finally: print("Finally block is executed.") ``` Error: division by zero Finally block is executed. 1. ZeroDivisionError:除以零錯誤 2. ValueError:值錯誤，例如轉換數據類型時的錯誤 3. TypeError:類型錯誤，例如將不支持的操作應用於特定類型的對象 4. FileNotFoundError:文件未找到錯誤，當試圖打開不存在的文件時引發
