Hi all,
after talking to Guido and Serhiy we present the next revision of this PEP. It is a compromise that we are all happy with, and a relatively restricted rule that makes additions to PEP 8 basically unnecessary.
I think the discussion has shown that supporting underscores in the from-string constructors is valuable, therefore this is now added to the specification section.
What about Fraction? Currently this is legal: py> Fraction("1/1000000") Fraction(1, 1000000) I think the PEP should also support underscores in Fractions: Fraction("1/1_000_000")
The remaining open question is about the reverse direction: do we want a string formatting modifier that adds underscores as thousands separators?
Yes please.
Open Proposals ==============
It has been proposed [11]_ to extend the number-to-string formatting language to allow ``_`` as a thousans separator, where currently only ``,`` is supported. This could be used to easily generate code with more readable literals.
