此名稱錯誤的其他解決方案不適用於我的代碼

Question

我無法解決這個問題。我閱讀了同樣的錯誤的一些答案，但他們的解決方案不起作用。我沒有想法。爲什麼發生錯誤？錯誤是：NameError：name'self'未定義

謝謝。

class irNum:

piApprox = irNum.approx(pi, 2, 2, 10 ** 3) 

print(piApprox)

有AA幾個錯字代碼：

那些我看到包括：

def __init__(self)不def__innit__(self)

特定的錯誤是可能從沒有通過自身來作爲參數get_approx

應該是get_approx(self, irNum, digitsNum, digitsDivider, cycles)
