Did you mean: 'attrA'?\n```\nThe correct suggestion is 'attrB', not 'attrA'.\n\nEvery time Python outputs suggestion for the name, it should first check whether the name is normalized. If it is not, Python should check if the normalized name exists, and suggest the normalized version, otherwise suggest names similar to the normalized version. It may be tricky, because the normalized came can look exactly like not normalized name (for example, 'µ' (`'\\xb5'`) and 'μ' (`'\\u03bc'`)). So we need to output also the `ascii()` of the name in that case.\n","author":{"url":"https://github.com/serhiy-storchaka","@type":"Person","name":"serhiy-storchaka"},"datePublished":"2026-01-17T14:12:25.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/143962/cpython/issues/143962"}
