[New-bugs-announce] [issue38530] Offer suggestions on AttributeError

[Pablo Galindo Salgado]

New submission from Pablo Galindo Salgado <pablogsal at gmail.com>:

To improve the debugging experience in both interactive and non-interactive code, I propose to offer suggestions when attribute access fails. For example:

>>> class A: foo = None
... 
>>> A.fou
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: type object 'A' has no attribute 'fou'

Did you mean: foo?

This also applies to imports from modules and other situations:

>>> import collections
>>> collections.NamedTuple
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'collections' has no attribute 'NamedTuple'

Did you mean: namedtuple?
