str.join(iterable)¶

Return a string which is the concatenation of the strings in the iterable

[issue13754] str.ljust and str.rjust do not exactly describes original string return

2012-01-09 Thread py.user 

New submission from py.user :

http://docs.python.org/py3k/library/stdtypes.html#str.ljust

str.ljust(width[, fillchar])¶

Return the string left justified in a string of length width. Padding is 
done using the specified fillchar (default is a space). The original string is 
returned if width is less than len(s).

str.rjust(width[, fillchar])¶

Return the string right justified in a string of length width. Padding is 
done using the specified fillchar (default is a space). The original string is 
returned if width is less than len(s).



"less than len(s)" -> "less than or equal to len(s)"

this problem is another
str.capitalize makes the first character big, but it doesn't make the rest small
clearing documentation is not enough

lowering works

If I want to change the pattern string by any delimiter, I should create a new

I would change the delimiter either in the object or in the class at any time

[issue8555] tkinter doesn't see _tkinter

2010-04-27 Thread py.user 

py.user  added the comment:

I have downloaded Python today (28 Apr) from the site
I have a version under WinXP (it works fine), but I don't use WinXP
When it told this about _tkinter, I even read the README file and compiled it 
with "make test", and there the same thing, it couldn't find _tkinter
as for Python2.5 it's allright, but it has another Tkinter, so sources are not 
portable

py.user  added the comment:

also strange(unobvious) behavior:

'>> '{0:.3s}'.format(range(10))
'ran'
>>> '{0:.3s}'.format(None)
'Non'

it would be better to print an error:

like in this:
>>> '{0:d}'.format(4.5)
Traceback (most recent call last):
  File "", line 1, in

in the documentation there is nothing about it

typically modifies the result."

"an empty format string ("")" what does it mean ?

"".format(value) or "{}".format(value) or "{0}".format(value) ?

this is an empty replacement field

here:
http://docs.python.org/py3k/library/string.html#format-string-syntax

the definition of format string:
"Format strings contain “replacement fields” surrounded by curly braces {}. 
Anything that is not contained in braces is considered literal text, which is 
copied unchanged to the output."

"The grammar for a replacement field is as follows:"
replacement_field ::=  "{" [field_name] ["!" conversion] [":" format_spec] "}"

I think, there should be a text in the documentation: "if the alignment optiont 
is invalid, it will be raised a ValueError exception"

[issue13838] In str.format "{0:#.5g}" for decimal.Decimal doesn't print trailing zeros

2012-01-22 Thread py.user 

New submission from py.user :

http://docs.python.org/py3k/library/string.html#format-specification-mini-language

The '#' option:
"For floats, complex and Decimal the alternate form causes the result of the 
conversion to always contain a decimal-point character, even if no digits 
follow it. Normally, a decimal-point character appears in the result of these 
conversions only if a digit follows it. In addition, for 'g' and 'G' 
conversions, trailing zeros are not removed from the result."

1)
>>> import decimal
>>> '{0:#.5g}'.format(1.5)
'1.5000'
>>> '{0:.5f}'.format(decimal.Decimal(1.5))
'1.5'
>>> '{0:.5g}'.format(decimal.Decimal(1.5))
'1.5'
>>> '{0:#.5g}'.format(decimal.Decimal(1.5))
'1.5'
>>>

no zeros with "#"

2)
>>> import decimal
>>> '{0:#.5g}'.format(decimal.Decimal('1.5000'))
'1.5000'
>>> '{0:.5g}'.format(decimal.Decimal('1.5000'))

This paragraph is redundant

a duplicate

[issue14155] Deja vu in re's documentation

2012-03-01 Thread py.user 

py.user  added the comment:

this sentence was deleted:
http://docs.python.org/py3k/library/re.html#matching-vs-searching
"The “match” operation succeeds only if the pattern matches
at the start of the string regardless of mode,
or at the starting position given by the optional pos argument
regardless of whether a newline precedes it."

this sentence exists now:
http://docs.python.org/dev/library/re.html#re.match
"Note that even in MULTILINE mode, re.match() will only match at the beginning 
of the string
and not at the beginning of each line."


but the multiline mode affects on regex.match()
a reader may confuse re.match() and regex.match(), although regex.match() cites 
to regex.search()

[issue14155] Deja vu in re's documentation

2012-03-01 Thread py.user 

py.user  added the comment:

I won't open another topic:
1)
http://docs.python.org/py3k/library/re.html#regular-expression-syntax
"Most of the standard escapes supported by Python string literals
are also accepted by the regular expression parser:

\a  \b  \f  \n
\r  \t  \v  \x
\\
"


\b can be used only in character set [], when others can be used without it

2)
http://docs.python.org/py3k/library/re.html#regular-expression-syntax
"Octal escapes are included in a limited form.
If the first digit is a 0, or if there are three octal digits,
it is considered an octal escape. Otherwise, it is a group reference.
As for string literals, octal escapes are always at most three digits in 
length."

http://docs.python.org/py3k/library/re.html#regular-expression-syntax
description of the back refference:
"\number
Matches the contents of the group of the same number.
Groups are numbered starting from 1. For example, (.+) \1 matches 'the the' 
or '55 55',
but not 'the end' (note the space after the group).
This special sequence can only be used to match one of the first 99 groups.
If the first digit of number is 0, or number is 3 octal digits long,
it will not be interpreted as a group match, but as the character with 
octal value number.
Inside the '[' and ']' of a character class, all numeric escapes are 
treated as characters."

py.user  added the comment:

the prefix "0x" is not necessary for the %x specifier in C
if the pattern will see "ABC", it will not match with it, but it should match

[issue14519] In re's examples the example with scanf() contains wrong analog for %x, %X specifiers

2012-04-14 Thread py.user 

py.user  added the comment:

the same problem in the %o analog

valid strings for the %x specifier of scanf():
"+0xabc"
"-0xabc"
"+abc"
"-abc"

valid strings for the %o specifier of scanf():
"+0123"
"-0123"
"+123"
"-123"

how to patch
the %x specifier:
0[xX][\dA-Fa-f]+   ->   [-+]?(0[xX])?[\dA-Fa-f]+
the %o specifier:
0[0-7]*->   [-+]?[0-7]+

[issue18206] There is no license.html on www.python.org

2013-06-13 Thread py.user 

New submission from py.user:

[guest@localhost ~]$ python3
Python 3.3.0 (default, Sep 29 2012, 22:07:38)
[GCC 4.7.2 20120921 (Red Hat 4.7.2-2)] on linux

answer from webmas...@python.org:

Hello,

When I use the version of Python distributed by python.org and type "license()" 
I get the full license text and not the url.

It seems like this might be a change made by Red Hat? Either way, the proper 
place to discuss issues like this is on the Python bug tracker:

http://bugs.python.org/

Feel free to report an issue there and the developers can look at it.

This email address is actually for reporting problems with the Python.org 
website!

All the best,

Michael Foord

[guest@localhost cpython]$ sed -n '453,456p' Lib/site.py

[issue18220] In itertools.islice() make prototype like in help()

2013-06-15 Thread py.user 

py.user added the comment:

same thing with range():
http://docs.python.org/3/library/stdtypes.html?highlight=range#range
http://docs.python.org/3//library/functions.html#func-range

and with slice():
http://docs.python.org/3/library/functions.html?highlight=slice#slice
http://docs.python.org/3//library/functions.html#slice

can't patch them, because comma doesn't get into brackets
"class range([start], stop[, step])"

[issue18220] In itertools.islice() make prototype like in help()

2013-06-21 Thread py.user 

py.user added the comment:

[guest@localhost cpython]$ ./python
Python 3.4.0a0 (default, Jun 22 2013, 04:24:17) 
[GCC 4.7.2 20121109 (Red Hat 4.7.2-8)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> 
>>> import itertools
>>> print(range.__doc__, slice.__doc__, itertools.islice.__doc__, 
>>> sep='\n***\n') 
range(stop) -> range object
range(start, stop[, step]) -> range object

Returns a virtual sequence of numbers from start to stop by step.
***
slice(stop)
slice(start, stop[, step])

Create a slice object.  This is used for extended slicing (e.g. a[0:10:2]).
***
islice(iterable, [start,] stop [, step]) --> islice object

Return an iterator whose next() method returns selected values from an
iterable.  If start is specified, will skip all preceding elements;
otherwise, start defaults to zero.  Step defaults to one.  If
specified as another value, step determines how many values are 
skipped between successive calls.  Works like a slice() on a list
but returns an iterator.

I have updated the patch
