一位教授告诉我,如果在Windows 98中执行此操作,则除以零或在Python崩溃中使用负平方根。
这似乎很荒谬,因为Python是一种解释性语言,但我没有办法验证这一点,Windows也是臭名昭着的......任何人都可以确认或否认这种说法吗?如果是这样,它是否与Python用C语言编写的事实有关? (并且C会真正使整个操作系统崩溃,除以零!?)

它应该导致ZeroDivisionError
异常。我无法想象为什么在Windows 98中这会有所不同。
>>> 1/0
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ZeroDivisionError: integer division or modulo by zero
多么浪费时间。

如果我没有错,我记得对于某些处理器系列(AMD?),除零会导致处理器循环并导致系统崩溃(在win 95和win 98上)。
也许你的教授指的是那个?
