我想讓文本淡入淡出，但它所做的是提供有關超出範圍的錯誤消息。我被告知使用colormode（255），但它不起作用。我不確定255是高還是高，但請幫忙。蟒龜色彩模式不工作

我測試了你的代碼，它可以在Python 2.7.10環境下使用Turtle 0.0.2正常工作。

我覺得你的問題是，你傳遞參數x/5在FADE_IN_OUT，並且必須使用python 3.你得到的錯誤，

_tkinter.TclError: expected integer but got "200.0"

抱怨接收浮動，而不是一個整數。嘗試使用Python 3的整數除法運算符//而不是單個/。

例如，調用FADE_IN_OUT這樣的：

FADE_IN_OUT("47 Studios", "center", "Arial", x//5, "normal", 2.5, 2.5, 5)

或者，嘗試運行你的代碼在Python 2
