Another reason in support of spaces (rather than underscores) to
separate digit groups: it's the only separator that follows the SI
standard for representing numbers:
… for numbers with many digits the digits may be divided into
groups of three by a thin space, in order to facilitate reading.
Neither dots nor commas are inserted in the spaces between groups
of three.

This isn't binding upon Python, of course. However, it should be a
consideration in choosing what separator convention to follow.
