Syntax keywords in general (`if`, `is`, `def`, `for`, `with`, etc.)\n2. Keywords that are variables (`True`, `False`, `None`)\n3. Imports in particular (`from`, `import`)\n\nI feel that distinguishing between 1 and 2 is more important than between 1 and 3. While `None` *is* a keyword, seeing it appear in the same color as `is` and other keywords feels odd.\n\n### Has this already been discussed elsewhere?\n\nThis is a minor feature, which does not need previous discussion elsewhere\n\n### Links to previous discussion of this feature:\n\n_No response_\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-135000\n* gh-138928\n* gh-138931\n* gh-138939\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/treyhunner","@type":"Person","name":"treyhunner"},"datePublished":"2025-05-30T22:54:21.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/134953/cpython/issues/134953"}
