{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Fraction literals should support underscores in numbers and whitespace around numbers","articleBody":"To make fraction literals more readable, this should be made to work:  `Fraction('31_415_925_535 / 10_000_000_000')`\r\n\r\n[PEP 515 – Underscores in Numeric Literals](https://peps.python.org/pep-0515/) are well supported in all numeric types except for fractions.   This works:  `1_234` and `Decimal('1_234')`.  However, this is not accepted:  `Fraction('1_234')`. \r\n\r\nLike decimals and ints, fractions support leading and trailing whitespace for string inputs:  `int(' 123 ')`, `Decimal(' 123.4 ')`, and `Fraction(' 123/100 ')`.  What is still needed is support for optional whitespace around the forward slash: `Fraction('355 / 113')`. This particular example came up when using the Fraction module to teach math to kids and where the string literal was obtained from calling `input()`.\r\n\r\nSide note: If you write `print(355/113)` in your code, Black will reformat it to `print(355 / 113)`. Because of this, I expect that adults will also develop a preference for writing fractions with whitespace around the slash.","author":{"url":"https://github.com/rhettinger","@type":"Person","name":"rhettinger"},"datePublished":"2022-08-30T15:52:23.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/96432/cpython/issues/96432"}
