Raymond Hettinger 44c42b9cf3 Added a tutorial note and example regarding the scope of loop variables 
in a list comprehension.  Includes a justification and a comparision
to regular for-loops.

 2002-09-06 18:06:04 +00:00
Raymond Hettinger a6e16a86c4 Replace all cases of "while 1" with "while True". 
Though slightly slower, has better clarity and teaching value.

Michael W. Hudson dd32a91cc0 This is my patch

Fred Drake 55ad7f84a4 Completely revise markup for the list of list methods; the new markup matches 
the semantics and presentation used in the library reference.
Added an explanation of the use of [...] to denote optional arguments, since
this is the only use of this in a signature line.
Closes SF bug #567127.
 2002-06-11 02:56:17 +00:00
Neal Norwitz d68f5171eb As discussed on python-dev, add a mechanism to indicate features 
that are in the process of deprecation (PendingDeprecationWarning).
Docs could be improved.
 2002-05-29 15:54:55 +00:00
Andrew M. Kuchling e7bd876f9d Message for NameError has changed 2002-05-02 14:31:55 +00:00
Fred Drake 38f71973e5 Documentation for the enumerate() function/type. 
This closes SF patch #547162.
 2002-04-26 20:29:44 +00:00
Fred Drake 6cb64f9e46 "Shortcut" should be "short-circuit". 
This closes SF bug #526277.
 2002-03-08 00:54:43 +00:00
Fred Drake c26467d53f Revise cheeseshop example so that the order of the keyword output is 
completely determined by the example; dict insertion order and the string
hash algorithm no longer affect the output.
This fixes SF bug #509281.
 2002-01-29 14:53:30 +00:00
Fred Drake 23d45f4744 Fix up some examples in the tutorial so we don't contradict our own 
advice on docstrings.
This fixes SF bug #495601.
 2001-12-20 23:54:56 +00:00
Fred Drake ecd8157a2c Include a warning that scripts should not have the same name as standard 
modules, or the module cannot be properly imported.  (Based on a suggestion
sent to python-docs.)

Update the displayed dir() of the sys and __builtin__ module with Python 2.2.
 2001-12-04 19:47:46 +00:00
Fred Drake 6016dbecca Talk about str() in the discussion of string representations of values, and 
give examples for which str() and repr() yield different results.
This closes SF bug #485446.
 2001-12-04 19:20:43 +00:00
Fred Drake fcf94681ed Update lambda description to reflect nested scopes. This was noted by 
Andrew Koenig.
 2001-12-03 21:47:37 +00:00
Fred Drake 1da50f6c6e Add a scalar product to the example list comprehensions based on a suggestion 
sent to python-docs.
 2001-12-03 18:54:33 +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
Fred Drake a815916472 Fix thinko in a comment about seeking with a file object. 
Reported by Francesco Trentini.
 2001-10-16 03:25:00 +00:00
Fred Drake 13af42822c Exceptions in interactive examlpes did not always include the indication of 
the source file using "in ?".

Added a description of the bare "raise" statement.

Added more description and examples for user-defined exceptions; this
is part of a response to SF bug #443559.
 2001-09-21 21:10:05 +00:00
Fred Drake ba5c41d4c5 Clarified the interaction between string literals and continuation lines. 
Fixes bug reported as SF bug #453728.
 2001-09-06 18:41:15 +00:00
Fred Drake 8b09f4985c Make the examples for "Default Argument Values" more presentable and 
less hostile to newbie use at the interactive prompt.
This is in response to SF bug #458654.
 2001-09-06 18:21:30 +00:00
Fred Drake d3ba10f4b5 Clarify the prompt in an example. 
This closes SF bug #450633.
 2001-08-14 19:55:42 +00:00
Fred Drake 20c94913de Minor re-wording in the exaplantion of sequence comparisons. 
This closes SF bug #445749.
 2001-08-01 17:17:13 +00:00
Fred Drake 01815526e0 Add a more substantial example startup file for the interactive shell; 
sample startup script provided by Itamar Shtull-Trauring.

This closes SF patch #410890.

Add some logical markup where it was missing.
 2001-07-18 19:21:12 +00:00
Fred Drake 17f690f96b Minor changes to match the style guide. 2001-07-14 02:14:42 +00:00
Fred Drake ed51494666 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.
 2001-07-06 17:28:39 +00:00
Fred Drake 88e66254f9 Use the more conventional "self" as the name of the self parameter in an 
example.  It actually confused a reader.
 2001-06-29 17:50:57 +00:00
Fred Drake d5df09cfb6 Update to include the license information in a less annoying place. 2001-06-20 21:37:34 +00:00
Tim Peters fa9e273442 Clarification in the fp appendix suggested on c.l.py by Michael Chermside. 
Also replaced a *star* style emphasis in the Representation Error section
with an \emph{} thingie.
 2001-06-17 21:57:17 +00:00
Fred Drake 7bc50714fe Fix the attributions for the new floating point text. 2001-06-08 17:09:01 +00:00
Fred Drake 8c27d99941 Added credits in the right places. 2001-06-08 16:28:53 +00:00
Fred Drake 417d667dd9 Text from Tim & Guido discussing floating point arithmetic and what users 
need to understand about the binary & decimal fp, so that representation
weirdness is documented somewhere.  This makes it easier to repond to "bug"
reports caused by user confusion & ignorance of the issues.

This closes SF patch #426208.
 2001-06-08 16:24:58 +00:00
Tim Peters bd695a716d Changed all the examples with ugly platform-dependent float output to use 
numbers that display nicely after repr().  From much doctest experience
with the same trick, I believe people find examples with simple fractions
easier to understand too:  they can usually check the results in their
head, and so feel confident about what they're seeing.  Not even I get a
warm feeling from a result that looks like 70330.345024097141 ...
 2001-05-22 06:54:14 +00:00
Fred Drake 8b0b8409ae Update output to reflect additional precision produced by the repr() of 
floating point numbers in an interactive example.


Added comment to help explain control flow in the example code showing
how to check if a number is prime.

This closes SF bugs 419434 and 424552.
 2001-05-21 16:55:39 +00:00
Fred Drake 9188b2194a Correct two floating-point representations printed by the interpreter in 
interactive examples.  Error noted by Dinu Gherman.
 2001-04-25 21:03:20 +00:00
Fred Drake 0c14961872 Update to reflect the new string repr -- \n instead of \012. This is the 
only documentation file that appears to be affected by the change!
 2001-04-12 04:26:24 +00:00
Fred Drake 5d6e402e0c Based on a comment by Konrad Hinsen on python-list: 
Change "EOF" to "end-of-file", on the premise that it is easier for
new programmers to understand (at least a little).

This does not attempt to explain "file or device attached to standard
input."
 2001-04-11 04:38:34 +00:00
Fred Drake 979d041b6f Make reference to the Library Reference in the "What Now?" chapter a 
hyperlink.

Fix two English usage errors caught by Jan Wells:  Changed "subsequence"
to "sub-sequence" in two places, and avoid improper use of "hopefully" in
the first paragraph of the "What Now?" chapter.
 2001-04-03 17:41:56 +00:00
Fred Drake 1b0b2a4df2 Add some LaTeX magic so that Latin-1 characters do not get so badly 
trashed.
 2001-03-13 17:56:08 +00:00
Fred Drake 67fdaa4883 Correct typos in Ping's email address. 
Remove premature use of negative indexes in string operation examples;
negative indexes have not been explained at that point, and the use of
negative indexes are not necessary for the examples.
 2001-03-06 07:19:34 +00:00
Fred Drake 162c6a637a Reflect change in traceback format: 
"innermost last" --> "most recent call last"
 2001-02-14 03:20:18 +00:00
Ka-Ping Yee 5401996638 Update to properly explain that the default Unicode encoding is ASCII, &c. 2001-02-13 22:20:22 +00:00
Ka-Ping Yee fa004ad36c Show '\011', '\012', and '\015' as '\t', '\n', '\r' in strings. 
Switch from octal escapes to hex escapes for other nonprintable characters.
 2001-01-24 17:19:08 +00:00
Fred Drake 0fe5af9b4d Clarify comments about returning None using a return without an expression; 
this is not hard to explain!

Closes SF bug #129345.
 2001-01-19 22:34:59 +00:00
Fred Drake cc97f8c609 Fix up an awkward sentence, pointed out by Chris Ryland <cpr@emsoftware.com>. 2001-01-01 20:33:06 +00:00
