執行結果：

繪製七段數碼管

seven digits draw v1.0 第一，繪製線 第二，繪製七段數碼管組成的數字 第三，繪製優化數碼管間距 第四，繪製多組數字 第五，獲取系統時間 第六，主函式執行程式。如下 import turtle as t import time def drawline draw drawgap ...

七段數碼管繪製

步驟1 繪製單個數字對應的數碼管 步驟2 獲得一串數字，繪製對應的數碼管 步驟2 獲得當前系統時間，繪製對應的數碼管 步驟1 繪製單個數字對應的數碼管 基本問題是繪製一條線，可將其定義為乙個基本函式 def drawline draw turtle.pendown if draw else turt...
