[issue41678] File-level, optionally external sorting

[Platon workaccount]

Platon workaccount <platon.work at gmail.com> added the comment:

I mean Python's analog of sort [-k x.y] table.txt from GNU Coreutils.

>> What do you refer when you say "sorting a file"?

Sorting a file with multi-line plain text. Optionally, text consisting of
several columns separated by a specific character.

>> What does "key" act upon? Strings representing the lines in the file?

This is a sort rule argument similar to that of the existing in-memory
sort()/sorted() method.

>> For allow_disk_use=False, what's the difference between opening the
file, reading the lines, using sort() and writing the contents?

If False, there is no difference.
