Forcing quote characters in repr(STRING), how?

[François Pinard]

Hi, people.

When using `repr()' on a string, Python automatically selects if it will
use single or double quotes to enclose the produced representation of
the string.  Is there a clean way to force that choice to be, under user
control, a particular quote character (either simple or double)?

                                Thanks in advance. :-)
