Hello,

I just tried the new attribute underscore_numbers with pprint, it doesn't work for me. I'm working on Windows.

Best regards,

Please do not post screen shots. They don't work for people with vision impairments, and we can't copy and past from them, so it makes it harder for us to help you.

It looks like it works with pformat, and not pprint:

>>> pprint.pformat(10000, underscore_numbers=True)
'10_000'
>>> pprint.pprint(10000, underscore_numbers=True)
10000

It's a bug in pprint.py. PR to follow shortly.
