IronPython 未按預期返回字典鍵

Question

我正在嘗試創建一個 q-table 作為在蚱蜢中填充隨機值的字典（一種使用 IronPython 作為解釋器的參數化設計工具）。 當我輸入如圖 1 所示的代碼時，我會收到一個字典，如圖2所示。 鍵顯然是不正確的，例如，第二個鍵包含一個 7 作為元組中的第一個元素。 該范圍內的許多值也丟失了。 我在蚱蜢之外嘗試了相同的代碼，我收到了預期的字典（圖 3 ）。 有人知道可能出了什么問題嗎？ 也許必須用泡菜做點什么？ 謝謝

code

    if not os.path.exists(r'C:\mygameqtable.pickle'):
            q_table = {}
            for i in range(-4, 5):
                for ii in range(-4, 5):
                    q_table[(i, ii)] = [random.uniform(-5, 0) for i in range(8)]
        
    else:
       with open(r'C:\mygameqtable.pickle', 'rb') as g:
           q_table = pickle.load(g)
        
    print q_table

Output

Answer 1

我建議您嘗試在列表理解中使用不同的變量名稱，例如“n”而不是“i”。

q_table[(i, ii)] = [random.uniform(-5, 0) for n in range(8)]

字典也沒有排序。 根據環境，您的“打印輸出”可能會按照它“希望”的任何順序列出密鑰。
