Python3.10 的 int 和 float 有什么隐性转换

Question

在 blender3.1 的更新日志关于 Python api 的部分看到了下面的内容：

Python 3.10

Python has been upgraded from version 3.9 to 3.10, there are some changes that may impact script authors.

• Python 3.10 no longer implicitly converts floats to int's (issue linked). This means functions that previously accepted float typed values will raise a type error.
  Floating point arguments must now be explicitly converted to integers (see example commits (rBAbb62f10, rBA7476c1a).

翻译一下就是:

Python 3.10

Python已经从3.9版本升级到3.10，有一些变化可能会影响到脚本作者。

Python 3.10 不再隐含地将浮点数转换为整数（问题链接）。这意味着以前接受浮点类型值的函数将引发一个类型错误。
浮点参数现在必须明确地转换为整数 (参见示例提交 (rBAbb62f10, rBA7476c1a)。

啥意思？是改了 feature 还是 修了 bug?

bpo-37999: No longer use int in implicit integer conversions.

No longer use implicit convertion to int with loss

Answer 1

REF: https://docs.python.org/3/wha...

Builtin and extension functions that take integer arguments no longer accept Decimals, Fractions and other objects that can be converted to integers only with a loss (e.g. that have the __int__() method but do not have the __index__() method).
