錯誤：未定義名稱「藍色」

Question

當用戶在hall()上選擇選項4時，它應該運行blue()，但是當我嘗試運行它時，出現錯誤，說明未定義blue()。我該如何解決？

Answer 1

不錯的故事btw）。無論如何，這個問題。 你調用函數blue（），它沒有在你的代碼中定義 - 沒有這樣的函數）。如果你的意思是叫藍天航空公司（），你會得到一個錯誤，那是因爲 首先需要使用前聲明函數它 例如：

1.this will not work: 
blue() 
def blue(): ... 

2. this will work: 
def blue(): ... 
blue() 

任何方式很好的做法其良好的保持簡單的代碼結構，上面的所有功能和主要是最後一個調用其他功能。

Answer 2

您收到錯誤的原因是因爲確實沒有定義名爲blue()的函數。這是你的代碼中的blue1()。我強烈建議投資棉絨。
