re the less important addition to my prev mail in http://docs.python.org/library/asyncore.html#asyncore-example-basic-http-cl… change self.buffer = 'GET %s HTTP/1.0\r\n\r\n' % path to self.buffer = 'GET {0} HTTP/1.0\r\nHOST: {1}\r\n\r\n'.format(path, host) this will get the real page (status 200) instead of "found" (302) page

by matthew chao Feb. 16, 2011

Feb. 16, 2011

version: Python 2.6 OS : Windows 7 The variable x below should have been 10(integer) after the expression evaluates. It ,however, gets the value 10.000000000000002 (float) , as follows, -------------------------------------------- >>> x=math.exp ( math.log(10.0)) >>> x 10.000000000000002 >>> x=math.exp ( math.log(10)) >>> x 10.000000000000002 -------------------------------------------- In mathematics, the result is not right.

> import bisect >>> scores = [(100, 'perl'), (200, 'tcl'), (400, 'lua'), (500, 'python')] >>> bisect.insort(scores, (300, 'ruby')) >>> scores [(100, 'perl'), (200, 'tcl'), (300, 'ruby'), (400, 'lua'), (500, 'python')] I thought instead of insort you meant insert. erden

Hello. Just wanted to notify you that the current ePub of the documentation doesn't load properly on Sony Readers. I'm not sure if it's a problem with my device, but for all I know it could be the ePub itself. Just giving you a heads up.

[issue11218] pattern=None when following documentation for load_tests and unittest.main()
by Martin von Gagern Feb. 15, 2011

Feb. 15, 2011

New submission from Martin von Gagern <Martin.vGagern(a)gmx.net>: If I follow the documentation at http://docs.python.org/library/unittest.html#unittest.main by putting the following two snippets of code in my module file: def load_tests(loader, standard_tests, pattern='test*.py'): # top level directory cached on loader instance this_dir = os.path.dirname(__file__) package_tests = loader.discover(start_dir=this_dir, pattern=pattern) standard_tests.addTests(package_tests) … [View More] return standard_tests if __name__ == "__main__": unittest.main() then the application will fail with an obscure error message: ====================================================================== ERROR: __main__ (unittest.loader.LoadTestsFailure) ---------------------------------------------------------------------- TypeError: object of type 'NoneType' has no len() ---------------------------------------------------------------------- Ran 1 test in 0.000s Monkeypatching unittest.loader._make_failed_load_tests to display a stack trace, I got this: Traceback (most recent call last): File "/usr/lib64/python2.7/unittest/loader.py", line 71, in loadTestsFromModule return load_tests(self, tests, None) File "tester.py", line 15, in load_tests package_tests = loader.discover(start_dir=this_dir, pattern=pattern) File "/usr/lib64/python2.7/unittest/loader.py", line 204, in discover tests = list(self._find_tests(start_dir, pattern)) File "/usr/lib64/python2.7/unittest/loader.py", line 247, in _find_tests if not self._match_path(path, full_path, pattern): File "/usr/lib64/python2.7/unittest/loader.py", line 235, in _match_path return fnmatch(path, pattern) File "/usr/lib64/python2.7/fnmatch.py", line 43, in fnmatch return fnmatchcase(name, pat) File "/usr/lib64/python2.7/fnmatch.py", line 75, in fnmatchcase res = translate(pat) File "/usr/lib64/python2.7/fnmatch.py", line 87, in translate i, n = 0, len(pat) TypeError: object of type 'NoneType' has no len() The error is due to the fact that pattern is passed as None to load_tests, but apparently loader.discover doesn't loke a None pattern. I would suggest that a) discover internally translates None to the default of 'test*.py' or b) the documentation is changed to cater for this common use case, i.e. by including a "pattern is None" case distinction in its load_tests snippet. In case b) is implemented but not a), it would be nice to have a more expressive error message by catching the error somewhat sooner. ---------- assignee: docs@python components: Documentation, Library (Lib) files: tester.py messages: 128579 nosy: docs@python, gagern priority: normal severity: normal status: open title: pattern=None when following documentation for load_tests and unittest.main() type: feature request versions: Python 2.7 Added file: http://bugs.python.org/file20763/tester.py _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11218> _______________________________________ [View Less]

[issue11209] Example for itertools.count is misleading

Feb. 14, 2011

New submission from Johannes Ammon <johannes.ammon(a)gmail.com>: The example code for itertools.count (http://docs.python.org/library/itertools.html#itertools.count) says # count(2.5, 0.5) -> 3.5 3.0 4.5 ...
