class Objects, values and types CPython implementation detail: For CPython, The standard type hierarchy User-defined functions __doc__ The function’s documentation string, or None if unavailable; not inherited by subclasses Writable __name__ The function’s name Writable __qualname__ The function’s qualified name New in version 3.3. Writable __module__ The name of the module the function was defined in, or None if unavailable. Writable __defaults__ A tuple containing default argument values for those arguments that have defaults, or None if no arguments have a default value Writable __code__ The code object representing the compiled function body. Writable __globals__ A reference to the dictionary that holds the function’s global variables — the global namespace of the module in which the function was defined. Read-only __dict__ The namespace supporting arbitrary function attributes. Writable __closure__ None ...
Python 條件敘述概念說明 參考 程式語言概念-條件敘述 條件敘述可用於對於程式某些變數的狀態進行判斷,並在該狀態執行特定工作,此種做有法助於程式結構化。 基本語法: Python的範例條件敘述如下: n = 3 if n < 0: print('n<0') elif n == 0: print('n==0') elif n == 2: print('n==2') else: print('Other') 在條件敘述加上變數單元中的比較運算,如果有兩個以上的條件可以加上邏輯運算。 if a > 0 and b > 0: print('a>b而且b>0') 程式碼說明 n 定義變數 if 如果,後面加條件 elif 其他條件,後面加條件 else 其他,後面不加條件 在條件式結尾必續加上:,下一行必須縮排,再加上要在該條件下,要執行的動作 投影片-slideshare:Python_條件敘述 影片-youtube:Python_條件敘述 程式碼-Github:條件敘述 下一單元: Python- 迴圈
