我知道错误是什么，但如果没有其他字符，为什么会显示此错误？我知道这个问题已被提出，但我找不到理由。
错误行代码：
Traceback (most recent call last):

顺便说一句，//不是注释，它是python中的除法以整数输出而不是浮点数，代码看起来也很拥挤，因为行必须在多长时间内有限制这个网站。我会将###放到错误行中引用。
我尝试调试它并以不同的方式接近它，但我找不到它为什么会这样做的原因。
答案 0 :(得分：1)
只是为了让你的调试工作，你正在尝试将空字符串转换为整数。要查看这出错的地方，您可能想要拆分：
array0, array1, array2 = (int(crypt_array0) // array0_key),
(int(crypt_array1) // array1_key), (int(crypt_array2) // array2_key) ###
到：
array0 = (int(crypt_array0) // array0_key)
array1 = (int(crypt_array1) // array1_key)
array2 = (int(crypt_array2) // array2_key)
通过这种方式，可以更轻松地了解到底出了什么问题。此外，请仅在将来发布相应的代码。
