$ python2.3 -c"import tempfile;print tempfile.mktemp()"
/tmp/tmpLmdDeT

Whatever the reason was, it was changed in Python 2.3 anyway.

The following excerpt from the documentation may also be of interest for you
and the OP:

"""
mktemp(
[suffix][, prefix][, dir])

Deprecated since release 2.3. Use mkstemp() instead.
 Return an absolute pathname of a file that did not exist at the time the
call is made. The prefix, suffix, and dir arguments are the same as for
mkstemp(). 

Warning: Use of this function may introduce a security hole in your program.
By the time you get around to doing anything with the file name it returns,
someone else may have beaten you to the punch.
