Guido van Rossum 77f6a65eb0 Add the 'bool' type and its values 'False' and 'True', as described in
PEP 285.  Everything described in the PEP is here, and there is even
some documentation.  I had to fix 12 unit tests; all but one of these
were printing Boolean outcomes that changed from 0/1 to False/True.
(The exception is test_unicode.py, which did a type(x) == type(y)
style comparison.  I could've fixed that with a single line using
issubtype(x, type(y)), but instead chose to be explicit about those
places where a bool is expected.

Still to do: perhaps more documentation; change standard library
modules to return False/True from predicates.

Fred Drake da8a6dd072 Added missing version annotation for dict(). 2002-03-06 02:29:30 +00:00
Tim Peters 9f4341b3b0 SF bug #501591: dir() doc is old
Bugfix candidate.

+ Updated dir() description to match actual 2.2 behavior.

+ Replaced the dir(sys) example with dir(struct), because the former
  was way out of date and is bound to change frequently, while the
  latter is stable.

+ Added a note cautioning that dir() is supplied primarily for
  convenience at an interactive prompt (hoping to discourage its
  use as the foundation of introspective code outside the core).

Fred Drake 526c7a0101 Ensure that complex() only accepts a string argument as the first arg,
and only if there is no second arg.
This closes SF patch #479551.

Fred Drake 5172adca81 Minor clarification of the zip() description, based on a comment sent to
python-docs.
2001-12-03 18:35:05 +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.

Fred Drake 0b66310476 When referring to a formal parameter from the description, use the name given
with the signature, not an ad hoc abbreviated form.
2001-11-07 06:28:47 +00:00
Fred Drake 66ded524ba apply() documentation: Remove a detail about the implementation that does
not affect the API.  Clean up the text about call syntax apply() is
equivalent to.  Based on comments by Thomas Guettler.

Tim Peters a427a2b8d0 Rename "dictionary" (type and constructor) to "dict". 2001-10-29 22:25:45 +00:00
Fred Drake ef7d08a661 Some style changes and typo fixes. 2001-10-26 15:04:33 +00:00
Tim Peters 1fc240e851 Generalize dictionary() to accept a sequence of 2-sequences. At the
outer level, the iterator protocol is used for memory-efficiency (the
outer sequence may be very large if fully materialized); at the inner
level, PySequence_Fast() is used for time-efficiency (these should
always be sequences of length 2).

dictobject.c, new functions PyDict_{Merge,Update}FromSeq2.  These are
wholly analogous to PyDict_{Merge,Update}, but process a sequence-of-2-
sequences argument instead of a mapping object.  For now, I left these
functions file static, so no corresponding doc changes.  It's tempting
to change dict.update() to allow a sequence-of-2-seqs argument too.

Also changed the name of dictionary's keyword argument from "mapping"
to "x".  Got a better name?  "mapping_or_sequence_of_pairs" isn't
attractive, although more so than "mosop" <wink>.

abstract.h, abstract.tex:  Added new PySequence_Fast_GET_SIZE function,
much faster than going thru the all-purpose PySequence_Size.

libfuncs.tex:
- Document dictionary().
- Fiddle tuple() and list() to admit that their argument is optional.
- The long-winded repetitions of "a sequence, a container that supports
  iteration, or an iterator object" is getting to be a PITA.  Many
  months ago I suggested factoring this out into "iterable object",
  where the definition of that could include being explicit about
  generators too (as is, I'm not sure a reader outside of PythonLabs
  could guess that "an iterator object" includes a generator call).
- Please check my curly braces -- I'm going blind <0.9 wink>.

abstract.c, PySequence_Tuple():  When PyObject_GetIter() fails, leave
its error msg alone now (the msg it produces has improved since
PySequence_Tuple was generalized to accept iterable objects, and
PySequence_Tuple was also stomping on the msg in cases it shouldn't
have even before PyObject_GetIter grew a better msg).

Marc-André Lemburg b5507ecd3c Additional test and documentation for the unicode() changes.
This patch should also be applied to the 2.2b1 trunk.
2001-10-19 12:02:29 +00:00
Fred Drake e0063d20a7 Update the documentation for the isinstance() function to reflect recent
changes in the implementation.
Indented all descriptions consistently.
2001-10-09 19:31:08 +00:00
Tim Peters 3899d74c10 Make clear that tuple() accepts the same kind of arguments as list(). 2001-10-04 06:53:20 +00:00
Tim Peters af5910f025 The execfile() docs imply it acts on locals same as exec. But in truth
it acts more like assigning to keys in locals(), i.e. modifications to
function locals aren't reflected in the locals when execfile() returns.

Tim Peters 1c33daf143 Correct docs for long(float). 2001-09-30 06:18:26 +00:00
Guido van Rossum 0d68246f01 Fix two typos in the text about compile(), and add two caveats from
recent user feedback: you must end the input with \n and you must use
\n, not \r\n to represent line endings.

Tim Peters 2e29bfbe1a Document new file() constructor, with the body of open()'s text, plus a

Tim Peters 7321ec437b SF bug #444510: int() should guarantee truncation.
It's guaranteed now, assuming the platform modf() works correctly.
2001-07-26 20:02:17 +00:00
Guido van Rossum bf5a774bcb On int/long to the negative int/long power, let float handle it
instead of raising an error.  This was one of the two issues that the
VPython folks were particularly problematic for their students.  (The
other one was integer division...)  This implements (my) SF patch
#440487.
2001-07-12 11:27:16 +00:00
Fred Drake 91f2f26d75 Fix up a few style nits -- avoid "e.g." and "i.e." -- these make
translation more difficult, as well as reading the English more
difficult for non-native speakers.

Fred Drake bc0b260a77 Minor markup cleaning, and one required fix in the unistr() description. 2001-01-18 18:09:07 +00:00
Marc-André Lemburg ad7c98e264 This patch adds a new builtin unistr() which behaves like str()
except that it always returns Unicode objects.

A new C API PyObject_Unicode() is also provided.

This closes patch #101664.

omission noted on c.l.py by Aahz Maruch.

Swapped the order of the descriptions of int() and intern() so that
int() comes first (the functions are in alphabetic order).
