我似乎无法弄清楚问题出在哪里，

错误：

Traceback (most recent call last):
  File "./miningScreensaver", line 171, in <module>
    miningScreensaver().loop.run()
  File "./miningScreensaver", line 81, in __init__
    self.rxAddress = self.getRxAddress
AttributeError: miningScreensaver instance has no attribute 'getRxAddress'

代码：

#! Python

    def __init__(self):

        return password[12:12+44-1] # "rpcpassword="+randomPW+"\n"

miningScreensaver().loop.run()

这让我很生气，方法调用和方法的拼写完全相同，解决其他人的问题也无济于事。

您有混合制表符和空格。将您的编辑器设置为显示空白，您会发现问题所在。使用该选项运行 python-tt会有所帮助。

使用“编辑”按钮快速检查表明您正在混合制表符和空格。

特别是，前几个方法miningScreensaver是由一堆空格缩进的，而其余的——包括 getRxAddress——是由一个制表符缩进的。因此，Python 认为这些方法是在类之外的，这意味着它们被编译为顶级函数，而不是miningScreensaver实例方法。

要解决此问题，请取消标记您的代码并手动清理缩进。

为避免将来出现这种情况，请使用更好的文本编辑器，并使用-tor-tt标志运行 Python，这样它会给您一个明显的关于不一致的制表符/空格使用的错误，而不是尝试解析代码并给您一个错误。不明白。
