[issue24112] %b does not work, as a binary output formatter

[Steven D'Aprano]

Steven D'Aprano added the comment:

This is not a bug, since %b is not supported in Python 2, only in Python 3:

https://docs.python.org/2/library/stdtypes.html#string-formatting-operations

No new features will be added to 2.7, so if you need %b you can use Python 3, 
or in Python 2.7 you can use the newer string format method instead:

py> "{:b}".format(42)
'101010'

New submission from Bob Stein:

`"%b"%42` produces a ValueError exception instead of outputting '101010'
