I've never needed them in Python, but I've very often wished for them
in C.  Along with 0b(0|1)* for binary numbers, where they'd be even
more useful.

Of course, I write _far_ more code in C than Python.  But I've seen
enough bugs of the sort where someone wrote 1200000 when they meant
12000000, that I see great value in being able to specify 12_000_000.
