[Python-checkins] CVS: python/dist/src/Lib/test test_pprint.py,1.2,1.3

2001年5月14日 11:39:43 -0700

Update of /cvsroot/python/python/dist/src/Lib/test
In directory usw-pr-cvs1:/tmp/cvs-serv1384/python/dist/src/Lib/test
Modified Files:
	test_pprint.py 
Log Message:
pprint's workhorse _safe_repr() function took time quadratic in the # of
elements when crunching a list, dict or tuple. Now takes linear time
instead -- huge speedup for even moderately large containers, and the
code is notably simpler too.
Added some basic "is the output correct?" tests to test_pprint.
