我在這段代碼中遇到錯誤: 錯誤發生在我的函數settings()中的Button()命令中。但我沒有任何計劃如何解決它,對不起。我不能把3個命令在外部功能,因爲它不會得到變量...Python:按鈕命令+'&'

請告訴我什麼,我做錯了//修復它請。
有什麼具體問題?你是否收到錯誤消息或堆棧跟蹤?你期望發生什麼?發生了什麼呢? – Chris 2014-09-05 17:05:01
另外,你的格式是* horrendous *。這段代碼是不可讀的。看看Python的官方風格指南[PEP 8](http://legacy.python.org/dev/peps/pep-0008/)。 – Chris 2014-09-05 17:06:26
我收到了一條錯誤消息。我想在一個按鈕命令中更改海龜的Shape,Shapesize和Pensize。 pensize不會改變,並且出現錯誤消息:「TypeError:不支持的操作數類型爲&:'NoneType'和'NoneType'」 – ProgrammingDonkey 2014-09-05 17:06:54
