[Python-checkins] CVS: python/dist/src/Lib/test test_complex.py,1.1,1.2

[Tim Peters]

Update of /cvsroot/python/python/dist/src/Lib/test
In directory usw-pr-cvs1:/tmp/cvs-serv11489/python/dist/src/Lib/test

Modified Files:
	test_complex.py 
Log Message:
This division test was too stringent in its accuracy expectations for
random inputs:  if you ran the test 100 times, you could expect it to
report a bogus failure.  So loosened its expectations.
Also changed the way failing tests are printed, so that when run under
regrtest.py we get enough info to reproduce the failure.
