Also, the dot after the first 'b' was confusing to me: I thought it had something to do with an attribute of b. And the quotes around the second 'b' were also confusing, but that's mostly because the original example initialized a class variable named 'b' with the str value 'b'.
Maybe a better error would use a colon:
AttributeError: foo: Did you mean: 'foo1'?
Looking at 3.10s behavior, I can't decide what logic it's using to suggest something:
>>> 'foo'.formatx
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'str' object has no attribute 'formatx'. Did you mean: 'format'?
>>> class C: pass
...
>>> C().a
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'C' object has no attribute 'a'
