python - Python 3 中的 sys.maxint 是什么？

Question

我一直在尝试找出如何表示最大整数，并且我已经阅读过使用 "sys.maxint"。但是，在 Python 3 中，当我调用它时，我得到:

AttributeError: module 'object' has no attribute 'maxint'

Answer 1

The sys.maxint constant was removed, since there is no longer a limit to the value of integers. However, sys.maxsize can be used as an integer larger than any practical list or string index. It conforms to the implementation’s “natural” integer size and is typically the same as sys.maxint in previous releases on the same platform (assuming the same build options).
