Jeremy Hylton f3255c8540 Reword explanation of global statement since an undeclared global is a
free variable and is subject to those rules.
2002-04-01 21:25:32 +00:00
Jeremy Hylton f0c1f1badb Note the sole case in which the ban on "from ... import *" within a
function is enforced.
2002-04-01 21:19:44 +00:00
Jeremy Hylton 15b68976da Remove the following restriction:
Names bound by import statements may not occur in global
    statements in the same scope.

Why not?
2002-04-01 21:18:02 +00:00
Jeremy Hylton d09ed68aeb Note that it is illegal to delete a cell variable.
Note that deleteing an unbound local will raise a NameError.
2002-04-01 21:15:14 +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
Jeremy Hylton e7d5773ed0 Update docs for nested scopes.
Replace section 4.1 with section A.3.

The new section 4.1 is titled "Naming and binding."  It includes the
text of section A.3 augmented with some of the detailed text from the
old section 4.1.

The \dfn, \index stuff is probably wrong, but I tried.

Also update other parts of appendix A to mention that nested scopes
and generators are standard features.
2002-04-01 20:38:01 +00:00
Jeremy Hylton 8392f36579 Update documentation of code objects.
Split the description of co_flags into two paragraphs.  The first
describes the flags that are used for non-future purposes, where
CO_GENERATOR was added.  The second describes __future__'s use of
co_flags and mentions the only one currently meaningful,
CO_FUTURE_DIVISION.
2002-04-01 18:53:36 +00:00
Jeremy Hylton 26c49b66bb Small fixes for description of function attributes.
func_closure is a readonly attribute.

Remove discussion of func_closure specific to 2.1.

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.

and \warning macros.
2001-12-14 22:52:41 +00:00

Fred Drake e31e9cebc0 Document generators and the yield statement, avoiding implementation details. 2001-12-11 21:10:08 +00:00
Fred Drake 1d3e6c15ce Fix whitespace in example of bad indentation: a comment indicated that one
line was not indented at all, so the example is no longer indented at all.
All of the errors being shown remain.

Typo: characteru --> character
2001-12-11 17:46:38 +00:00
Fred Drake f9d580346b Add change notes where im_class is discussed, since the exact meaning changes
with Python 2.2.
2001-12-07 23:13:53 +00:00
Guido van Rossum b62f0e1a7b Correct the description of im_class. (Fred, this is changed in 2.2.
Should this be labeled as changed?  How?)
2001-12-07 22:03:18 +00:00
Fred Drake c2f496a138 Add a note to the description of the interaction between the softspace
attribute of file objects, the print statement, and other file operations.
This closes SF bug #484857.

Fix minor markup nits.
2001-12-05 05:46:25 +00:00
Guido van Rossum 4ed6be7107 Import the keyword module instead of relying on our own list of
reserved words.  No longer need to import string.
2001-12-04 20:39:36 +00:00
Guido van Rossum 41c6719fe4 Put the keywords back in alphabetical order. Apparently somebody
didn't use reswords.py, as the comment clearly states. :-(
2001-12-04 20:38:44 +00:00
Fred Drake 3570551d6f Remove most references to __members__ and __methods__, leaving only one pair
of references that now state that these attributes have been removed,
directing the reader to the dir() function.
This closes SF bug #456420.
2001-12-03 17:32:27 +00:00
Fred Drake c37b65ee10 Clean up some markup cruft. A number of the macros that take no
parameters (like \UNIX) are commonly entered using an empty group to
separate the markup from a following inter-word space; this is not
needed when the next character is punctuation, or the markup is the
last thing in the enclosing group.  These cases were marked
inconsistently; the empty group is now *only* used when needed.
2001-11-28 07:26:15 +00:00
Jeremy Hylton 1336e99054 Fred observes that the typo was not the only problem with this sentence. 2001-11-14 21:38:13 +00:00
Jeremy Hylton 4a98f70a09 typo 2001-11-14 21:32:27 +00:00
Fred Drake 08fd51509c When describing "import *", add a level of indirection between "*" and the
set of names imported (the "public names"), adding a definition of "public
names" that describes the use of __all__.
This closes SF bug #473986.

Flesh out the vague reference to __import__().
2001-10-24 19:50:31 +00:00
Fred Drake 0aa811c527 Use the \note and \warning macros where appropriate. 2001-10-20 04:24:09 +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 73921b0eec Refer to the objects which define __len__(), __*item__(), and __iter__()
as container objects rather than as mapping objects (in the index entries).
Change the section heading and intro sentence to be a little more general,
since that's how things have actually evolved.
2001-10-01 16:32:13 +00:00

conversion.

I'll work on it again when it's not so late...
2001-08-08 05:37:21 +00:00
Fred Drake 8dd6ffd0ec User-defined methods *can* contain things other than user-defined functions
as the callable, so use more flexible language.
2001-08-02 21:34:53 +00:00
Fred Drake 044bb4d22a Explain that __init__() methods do not get to return values. 2001-08-02 15:53:05 +00:00
Fred Drake 9079164bdf Removed unnecessary section "Unicode literals"; all the discussion is
already present in the "String literals" section, including comments on
the "u" prefix and the additional escape sequences used for Unicode.

This relates to SF bug #442526.
2001-07-20 15:33:23 +00:00
Fred Drake 0825dc2427 Fix typo in description of raw strings: "value" --> "valid"

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.

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.

the availability of nested scoping in Python 2.1 and 2.2.
2001-06-05 02:17:02 +00:00
Fred Drake 597bc1d46f Bring the notes on the relationship between __cmp__(), __eq__(), and
__hash__() up to date (re: use of objects which define these methods

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.
