Ok nice. Now another question :-)
Would it be useful to add an option to repr(int) and repr(float), or a
formatter to int.__format__() and float.__float__() to add an
underscore for thousands. Currently, we have the "n" format which
depends on the current LC_NUMERIC locale:
>>> '{:n}'.format(1234)
'1234'
>>> import locale; locale.setlocale(locale.LC_ALL, '')
'fr_FR.UTF-8'
>>> '{:n}'.format(1234)
'1 234'
My idea:
>>> (1234).__repr__(pep515=True)
'1_234'
>>> (1234.0).__repr__(pep515=True)
'1_234.0'
or maybe:
>>> '{:pep515}'.format(1234)
'1_234'
>>> '{:pep515}'.format(1234.0)
'1_234.0'
I don't think that it would be a good idea to modify repr() default
behaviour, it would likely break a lot of applications.
