unescape HTML entities

[Rares Vernica]

Hi,

How can I unescape HTML entities like " "?

I know about xml.sax.saxutils.unescape() but it only deals with "&", 
"<", and ">".

Also, I know about htmlentitydefs.entitydefs, but not only this 
dictionary is the opposite of what I need, it does not have " ".

It has to be in python 2.4.

Thanks a lot,
Ray

Hi,

How does your code deal with ' like entities?

Re: unescape HTML entities

[Rares Vernica]

Hi,

Nice module!

I downloaded 2.3 and I started to play with it. The file names have 
funny names, they are all caps, including extension.

For example the main module file is "SE.PY". Is you try "import SE" it 
will not work as Python expects the file extension to be "py".

Thanks,
Ray

Re: unescape HTML entities

[Rares Vernica]

Hi,

I downloades 2.2 beta, just to be sure I have the same version as you 
specify. (The file names are no longer funny.) Anyway, it does not seem 
to do as you said:

In [14]: import SE

In [15]: SE.version
---> SE.version()
Out[15]: 'SE 2.2 beta - SEL 2.2 beta'

In [16]: HTM_Decoder = SE.SE ('HTM2ISO.se')

In [17]: test_string = '''

Re: Physical constants

[Rares Vernica]

Hi,

I am not sure how the constants are implemented in math, but here is how 
I would do it. The main idea is to declare the constants as globals in 
some file.

Declare all the constants in a file:
const.py
---
pi = 3.14

Whenever you want to use pi from another file, just do:
somecode.py
---
from const import pi

a = 2 * pi

Ray

Check out some examples:

remove a list from a list

[Rares Vernica]

Hi,

I have the following problem:

I have a list like
   e = ['a', 'b', 'e']
and another list like
   l = ['A', 'a', 'c', 'D', 'E']
I would like to remove from l all the elements that appear in e 
case-insensitive. That is, the result would be
   r = ['c', 'D']

What is a *nice* way of doing it?

Thanks a lot,
Ray

Re: remove a list from a list

[Rares Vernica]

That is a nice solution.

But, how about modifying the list in place?

That is, l would become ['c', 'D'].

Thanks a lot,

Yeah, I ended up doing a similar kind of loop. That is pretty messy.

Is there any other way?

Re: remove a list from a list

[Rares Vernica]

Sorry for not being clear from the beginning and for not using clear 
variable names.

Problem context:

import os
dirs_exclude = set(('a', 'b', 'e'))
for root, dirs, files in os.walk('python/Lib/email'):
 # Task:
 # delete from "dirs" the directory names from "dirs_exclude"
 # case-insensitive

The solution so far is:

for i in xrange(len(dirs), 0, -1):
   if dirs[i-1].lower() in dirs_exclude:
 del dirs[i-1]

I am looking for a nicer solution.

Thanks a lot,
Ray

Re: remove a list from a list

[Rares Vernica]

The problem with skipping over them is that "walk" would still walk them 
and their content. If they have a lot of other dirs and files inside 
then this might end up being time consuming.

This solution I think is pretty nice:

source[:] = [x for x in source if x.lower() not in target]

re.search

[Rares Vernica]

Hi,

Isn't the following code supposed to return ('1994')?

 >>> re.search('(\d{4})?', '4 1994').groups()
(None,)

Thanks,
Ray

Unicode error handler

[Rares Vernica]

Hi,

Does anyone know of any Unicode encode/decode error handler that does a 
better replace job than the default replace error handler?

For example I have an iso-8859-1 string that has an 'e' with an accent 
(you know, the French 'e's). When I use s.encode('ascii', 'replace') the 
'e' will be replaced with '?'. I would prefer to be replaced with an 'e' 
even if I know it is not 100% correct.

If only this letter would be the problem I would do it manually, but 
there is an entire set of letters that need to be replaced with their 
closest ascii letter.

Is there an encode/decode error handler that can replace all the 
not-ascii letters from iso-8859-1 with their closest ascii letter?

Thanks a lot,
Ray

It does the job.

Thanks a lot,

Re: locale, format monetary values

[Rares Vernica]

That's it. Thanks a lot!

There is no example on the locale.format in the docs so I was confused.

Ray

Re: which datastructure for fast sorted insert?

[Rares Vernica]

use a set to store them:

>>> s=set()
>>> s.add('a')
>>> s.add('b')
>>> s
set(['a', 'b'])
>>> s.add('a')
>>> s
set(['a', 'b'])
>>> s.add('c')
>>> s
set(['a', 'c', 'b'])
>>> 

it does remove duplicates, but is it not ordered. to order it you can
use:

>>> l=list(s)
>>> l.sort()
>>> l
['a', 'b', 'c']

hth,
Rares

readline support

[Rares Vernica]

Hi,

I am trying to get readline support in python.

I am working on Linux and I have the latest version from svn. After I 
./configure and make I can run python, but the readline support is not 
there.

If I do:
%./configure >& out.txt
%grep readline out.txt
checking for readline in -lreadline... yes
checking for rl_callback_handler_install in -lreadline... yes
checking for rl_pre_input_hook in -lreadline... yes
checking for rl_completion_matches in -lreadline... yes

it seems that readline library is there and is found by python.

How can I further track down this issue?

Thanks,
Ray

locale, format monetary values

[Rares Vernica]

Hi,

Can I use locale to format monetary values? If yes, how? If no, is there 
something I can use?

E.g.,
I have 1 and I want to get "$10,000".

Thanks,
Ray
