> Yury, can you help me understand why `hasattr("foo", "bar")` triggers the infinite loop there, but not `print("foo")`?
hasattr uses getattr under the hood. getattr raises an AttributeError, and that triggers PyErr_SetError, which has an infinite "while" loop. Instead of "hasattr" you can use anything that raises an error. |
