Neal Norwitz f9f61b4aa2 Note version added for conditional expressions 2006-02-27 16:31:12 +00:00
Thomas Wouters dca3b9c797 PEP 308 implementation, including minor refdocs and some testcases. It 
breaks the parser module, because it adds the if/else construct as well as
two new grammar rules for backward compatibility. If no one else fixes
parsermodule, I guess I'll go ahead and fix it later this week.

The TeX code was checked with texcheck.py, but not rendered. There is
actually a slight incompatibility:

>>> (x for x in lambda:0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: iteration over non-sequence

changes into

>>> (x for x in lambda: 0)
  File "<stdin>", line 1
    (x for x in lambda: 0)
                     ^
SyntaxError: invalid syntax

Since there's no way the former version can be useful, it's probably a
bugfix ;)

Alex Martelli c516b0e47c clarified (in the 5.14 summary) that tests and comparisons all chain, 
added a specific \ref to 5.9 in lieu of previous vague "see above".
(same as commit of Sun Nov 2 to the release23-maint branch)

face of section re-ordering)
- fix minor markup nits for better presentation
 2003-09-06 03:33:32 +00:00
Fred Drake 25b5358cf2 Add definitions of the test and testlist symbols in the grammar so 
there are no gaps in the definitions.
Closes SF bug #726150.

Raymond Hettinger d0cda1dc9f SF patch #760792: "wo" in "word" now valid but not documented as such 
Revised version of a contribution from Gerrit Holl.

Update the docs for the extended behavior of __contains__
 2003-06-26 19:32:10 +00:00
Raymond Hettinger daa340418b * Fixed an unmatched parenthesis early in the text. 
* Clarified the meaning of lexicographic sequence ordering as discussed on
  comp.lang.python:  http://groups.google.com/groups?th=e163c9f9ba114493
 2003-06-26 17:41:40 +00:00

  follow strict LTR evaluation.

* Doc/ref/ref5.tex
  Documented the general LTR evaluation order idea.

 2002-12-16 13:54:02 +00:00
Gustavo Niemeyer f955412130 * Doc/ref/ref5.tex 
Fixed minor bug preventing documentation compilation.
 2002-11-26 18:14:35 +00:00
Tim Peters 5b21df4a5c Repaired inaccuracies in the % docs. In particular, we don't (and can't) 
guarantee abs(x%y) < abs(y) in all cases when a float is involved.
math.fmod() should, though, so noted that too.

Bugfix candidate.  Someone should check the LaTeX here first, though.

Fred Drake ce5619e8a1 Update: Older versions of Python crashed when calling repr() 
(including the implied call using back-ticks) of a recursive object,
but this is no longer the case.
Reported by Manus Hand via email.
 2002-11-13 15:32:34 +00:00
Raymond Hettinger 0da7f39a7c Closes SF bug #634069 reporting the docs on the ** operator were out 
of date and did not reflect the current CPython implementation.
 2002-11-08 05:30:23 +00:00
Raymond Hettinger 463bfafd24 Clarify deprecation of the floor div operator, modulo operator, 
and divmod() function for complex numbers.

Closes SF Bug 621708: Unclear deprecation.
 2002-10-11 21:08:02 +00:00
Fred Drake 74653820e3 Modified presentation of the grammar for calls to be easier to read 
for both HTML and typeset renderings.  Corresponds to revision
1.53.4.8 on the r22-maint branch.
 2002-10-07 16:28:38 +00:00
Raymond Hettinger 7fd9ced4ca Minor English grammar correction 2002-06-25 04:04:14 +00:00
Fred Drake e08c9dbffc Simplify the production for argument list, making sure that it 
actually allows all the legal syntax, and nothing else.  Previously,
it did not allow a call like func(arg, **dictionary).
This closes (again!) SF bug #493243.
 2002-06-20 14:23:15 +00:00
Fred Drake 074712112b Played contortionist games with the argument_list production so it 
might be easier to understand.
This relates to SF bug #493243, which will be closed.
 2002-06-18 18:42:01 +00:00
Raymond Hettinger 6cf09f0792 Patch 543387. Document deprecation of complex %, //,and divmod(). 2002-05-21 18:19:49 +00:00
Fred Drake af93c4c8d9 Added a missing "|" in the grammar productions used in the reference manual 
(reported by François Pinard).
Added some missing "_" characters in the same cluster of productions.
Added missing floor division operator in m_expr production, and mention
floor division in the relevant portion of the text.
 2002-04-30 02:18:51 +00:00
Fred Drake fd867719bc Fix typo: coverted --> converted. Reported by Francois Pinard. 2002-04-09 14:39:10 +00:00
Jeremy Hylton 2225add242 Given lambda its own section, instead of burying it in boolean operators. 2002-04-01 21:05:21 +00:00
Jeremy Hylton 53ed917d3a Update / simplify Identifiers section for nested scopes. 
How do I create a cross reference to section 4.1?
 2002-04-01 20:52:24 +00:00
Fred Drake f6eafc3fe1 Fix up unescaped tilde; reported by several people. 2002-03-18 16:47:14 +00:00
Fred Drake 83d14c12a6 Markup error: braces not properly marked in dictionary display 
grammer productions.
Fixes SF bug #520959.
 2002-03-16 06:35:54 +00:00
Fred Drake 5381588073 Revise the markup related to the grammar productions to increase the 
level of predictability.  This is not really "good" markup, but is arguably
better than we had before.
This closes SF bug #523117.
 2002-03-15 23:21:37 +00:00
Fred Drake b062cb22d0 Work around the problem of spaces after a "}" being dropped by LaTeX2HTML if 
they were represented by newlines in the document source.
Partially fixes SF bug #493243.
 2001-12-14 16:57:31 +00:00
Michael W. Hudson 850d3980ab Fix for 
[ #429329 ] actual-parameters *arg, **kws not doc'd
 2001-12-12 11:56:33 +00:00
Tim Peters 1350c07de3 Removed stray backslash (a typo -- my fault). 2001-10-01 20:25:26 +00:00
Tim Peters 20524dbf36 The description of dictionary comparison was out of date. Rather than 
try to explain the complex general scheme we actually use now, I decided
to spell out only what equality means (which is easy to explain and
intuitive), leaving the other outcomes unspecified beyond consistency.
 2001-10-01 20:22:45 +00:00
Fred Drake cb4638a278 Change the grammar productions to use the new productionlist environment; 
this supports a hyperlinked version of the grammar that can make tracking
down details and definitions a little easier.
 2001-07-06 22:49:53 +00:00
Fred Drake deda9f3420 Use a named reference to another chapter instead of hard coding the 
chapter number.  This also makes the reference a hyperlink in the HTML
version.
 2001-06-23 06:06:21 +00:00
Fred Drake 2829f1cf99 Fix a very minor (but annoying when looking for things!) markup nit. 2001-06-23 05:27:20 +00:00
Fred Drake 88382696f4 Update a "Programmer's note" about lambda forms and scoping to reflect 
the availability of nested scoping in Python 2.1 and 2.2.
 2001-06-05 02:17:02 +00:00
Fred Drake b8ac0096b2 Fix the operator precedence table: exponentiation binds tighter than 
negation.

This closes SF bug #421999.
