我是新學習python，我試圖用標準Tkinter庫創建一個計算器。每次我嘗試建立我遇到以下錯誤：Python 3遇到[解碼錯誤 - 輸出不是utf-8]（崇高文本2）
File "C:\Python33\calc.py", line 10
[Decode error - output not utf-8]
[Finished in 0.1s with exit code 1]
構建系統是站在蟒蛇，或者我需要改變pyhton的其包內的東西嗎？ 感謝提前:)
這裏是我的代碼：

buttonText = ["1", "2", "3", "+", "4", "5", "6", "-", "7", "8", "9", "*", "0", ".", "=", "/"]
