Agreed, but that is actually not related with the suggestions. We only append a string at the end of whatever exception it was there. This difference is based on the attribute error for a slot not initialized vs an attribute error for something that is not there. For example, in 3.9:
---
class E:
__slots__=('blech')
E().blech
Traceback (most recent call last):
File "/home/pablogsal/github/cpython/lel.py", line 6, in <module>
E().blech
AttributeError: blech
while
class E:
__slots__=('blech')
E().bluch
Traceback (most recent call last):
File "/home/pablogsal/github/cpython/lel.py", line 4, in <module>
E().bluch
AttributeError: 'E' object has no attribute 'bluch'
