Fixed minor bug preventing documentation compilation.

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.

Raymond Hettinger 0da7f39a7c Closes SF bug #634069 reporting the docs on the ** operator were out 
of date and did not reflect the current CPython implementation.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.

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.

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.

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.
 2001-05-09 16:51:49 +00:00
Guido van Rossum 0dbb4fba4c Implement, test and document "key in dict" and "key not in dict". 
I know some people don't like this -- if it's really controversial,
I'll take it out again.  (If it's only Alex Martelli who doesn't like
it, that doesn't count as "real controversial" though. :-)

That's why this is a separate checkin from the iterators stuff I'm
about to check in next.
 2001-04-20 16:50:40 +00:00
Fred Drake 24e7a29292 Work around the conversion of ">>" and "<<" to guillemets. Reported by 
Ping on the Doc-SIG mailing list.
 2001-04-12 12:37:03 +00:00
Fred Drake ac79e95167 Re-word the explanation of the in/not in operators for increased content 
and clarity.

Add a footnote to the information on the possibility of shadowing builtins
with locals & module globals.
 2001-03-06 07:32:11 +00:00
Fred Drake 34bafcc079 Fix a variety of minor nits and typos caught by Chris Ryland 
<cpr@emsoftware.com>.
 2001-01-14 02:57:14 +00:00
Fred Drake 2a22200ab4 Adjust explanation of operator precedence summary -- exponentiation groups 
from right to left!

Closes bug #125391.
 2000-12-11 22:39:24 +00:00
Fred Drake c3b18d7ca8 Fix error noted by Gerrit Holl (old; had been buried in my INBOX): 
sequence repitition works just fine with long integers now, so we
should not say that only plain integers are allowed.
 2000-12-07 04:54:02 +00:00

Create a hyperlink between the language reference and documentation for
the built in functions.
 2000-07-31 20:08:23 +00:00
Fred Drake 7399b9e6e4 Moshe Zadka <mzadka@geocities.com>: 
Update the "in" / "not in" description to accomodate the current use
of the __contains__() discipline.  This patch also incorporates
suggestions from Marc-Andre Lemburg <mal@lemburg.com>, minor markup
revisions from Fred Drake, and some rewording of the first affected
paragraph (also from Fred).

Closes SourceForge patch #100831.
 2000-07-11 19:43:47 +00:00
