Re: [ python-Bugs-1215887 ] String and list methods deeply hidden
SourceForge.net wrote this on Mon, Jun 06, 2005 at 11:16:19AM -0700. My reply is below. The way the docs are written makes perfect sense to me ~ now ~ but I too had difficulty navigating them at first, particularly with finding the methods of sequence types from the TOC. Eventually, I must have looked them up in the alphabetic index and backtracked to find the appropriate TOC headings. Isn't that what everyone does? I think that's what everyone should do! Not being a "C" programmer, I must refer to "2.3.6.2 String Formatting Operations" continually, and I'm not complaining that it's not buried under "2.3.6.1 String Methods." Exposing the fourth level of subtopics in section 2.3 of the lib.html document would be nice, though. -- ..

[issue6978] compiler.transformer dict key bug d[1,] = 1
Chuck Rhode added the comment:
Here are four ways to generate things called in the documentation Abstract
Syntax Trees (ASTs). Obviously they are not all the same kind of object:
#!/usr/local/bin/python2.6
import sys
import compiler
import parser
import ast
STATEMENT = 'd[1,] = 2'
print 'level %s' % sys.version
print compiler.parse(STATEMENT)
print parser.suite(STATEMENT).tolist()
print ast.dump(
compile(STATEMENT, '', 'exec', ast.PyCF_ONLY_AST),
annotate_fields=False,
include_attributes=False,
)
print ast.dump(
ast.parse(STATEMENT),
annotate_fields=False,
include_attributes=False,
)

To me the *compiler* module has vestigial utility. It would be nice if it
returned correct results.

[issue7210] Proposed Syntax Checks in Test Suite
New submission from Chuck Rhode : PythonTidy is a code beautifier written three years ago and downloaded numerous times. o http://lacusveris.com/PythonTidy/PythonTidy.python It suffers a bug, which has only recently come to light. It considers the following lines equivalent: if False is (2 is 3): pass if False is 2 is 3: pass They're not. PythonTidy handles other non-associative operators such as division correctly. I was unable to generalize from arithmetic operators to comparison operators because the Abstract Syntax Tree (AST) generated by the *compiler* module returns a different structure for them. I tested PythonTidy by running the Python Test Suite (the *test* module scripts) through it and executing the results, thought I had all my bases covered because most tests succeeded, and missed this case, so I am suggesting an amplification of the Python Test Suite for developers who may be using it for purposes other than testing Python. I wish to add these lines to the foot of *test_grammar.py*. verify(16 // (4 // 2) == 8, '16 // (4 // 2) == 8') verify((16 // 4) // 2 == 2, '(16 // 4) // 2 == 2') verify(16 // 4 // 2 == 2, '16 // 4 // 2 == 2') verify((False is (2 is 3)) == True, '(False is (2 is 3)) == True') verify(((False is 2) is 3) == False, '(((False is 2) is 3) == False') verify((False is 2 is 3) == False, '(False is 2 is 3) == False') -- components: Tests files: test_grammar.patch keywords: patch messages: 94501 nosy: ChuckRhode severity: normal status: open title: Proposed Syntax Checks in Test Suite type: feature request versions: Python 2.5 Added file: http://bugs.python.org/file15206/test_grammar.patch ___ Python tracker <http://bugs.python.org/issue7210> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
