New format specifiers for string formatting of floats with SI and IEC prefixes

[guido (Guido van Rossum)]

@guido, I wasn’t suggesting adding the package to the standard library.

Sorry, the boundaries between the built-ins and the stdlib are often fuzzy, and core dev terminology often lumps them together under stdlib.

@avylove

I think it’s a common enough problem and generic enough to be considered.

I think you will have to argue this more forcefully and with data before it will be considered. Without that I feel that people who like to format their numbers in different ways can easily use a 3rd party package like yours to do the formatting for them.
