Only test which imports random module fails.

Your problem is that you have theLib/test/bisect.py file. I renamed it toLib/test/bisect_cmd.py.Workarounds:* Run the test using: ./python -m test test_xmlrpc* RenameLib/test/bisect.py toLib/test/bisect_cmd.pyThis bug is already fixed in the 2.7. You have to wait for the next 2.7 release to get the fix.

Okay, thanks, Victor. Your suggestion to renameLib/test/bisect.py toLib/test/bisect_cmd.py works. My question is why you fixed in 2.7 branch only? This problem persists in master (3.8).Ah, I think because I use cpython2 directory name, you thought I used Python 2. cpython2 is just a directory name. It has nothing to do with Python 2. I used master when finding this bug.

I used master when finding this bug.Ah right, I can reproduce the issue in master:vstinner@apu$ ./pythonLib/test/test_xmlrpc.py Traceback (most recent call last):  File "Lib/test/test_xmlrpc.py", line 8, in <module>    import xmlrpc.client as xmlrpclib  File "/home/vstinner/prog/python/master/Lib/xmlrpc/client.py", line 136, in <module>    import http.client  File "/home/vstinner/prog/python/master/Lib/http/client.py", line 71, in <module>    import email.parser  File "/home/vstinner/prog/python/master/Lib/email/parser.py", line 12, in <module>    from email.feedparser import FeedParser, BytesFeedParser  File "/home/vstinner/prog/python/master/Lib/email/feedparser.py", line 27, in <module>    from email._policybase import compat32  File "/home/vstinner/prog/python/master/Lib/email/_policybase.py", line 9, in <module>    from email.utils import _has_surrogates  File "/home/vstinner/prog/python/master/Lib/email/utils.py", line 28, in <module>    import random  File "/home/vstinner/prog/python/master/Lib/random.py", line 47, in <module>    import bisect as _bisect  File "/home/vstinner/prog/python/master/Lib/test/bisect.py", line 27, in <module>    import tempfile  File "/home/vstinner/prog/python/master/Lib/tempfile.py", line 45, in <module>    from random import Random as _RandomImportError: cannot import name 'Random' from 'random' (/home/vstinner/prog/python/master/Lib/random.py)Hum. We should either renameLib/test/bisect.py toLib/test/bisect_cmd.py or move the feature into libregrtest.
