Re: [Tutor] Removing Content from Lines....
Hello everyone,
First time using the mailing list to give a suggestion, apologies in
advance if it's not appropriate :)
Considering you're looking for specific string, I'd recommend maybe looking
into the Regular Expressions. You could use something like:
#At the top of the file
import re
#Within your function
target = open(filename, 'rU')
# This will read the file as a whole string, careful, it loads the file
into memory so if it's a big file, it might cause troubles
text = target.read()
# The regular expression should match every single tag and its content
within the file, using '.*?' will match each character without being greedy.
match = re.findall(r'.*?', text)
Afterwards, you can use something like:
for i in match:
print i
This should print out all the matches to Stdout so you can verify the RegEx
behaves as expected. To write the matches in a new file, you could do:
new = open('Matches', 'w') ## This will create a new file called
'Matches' for writing
for i in match:
new.write(i + '\n') ## Each match of the RegEx will be written on a new
line in the Matches file.
At the end, my function looks like this:
def textfind(filename):
target = open(filename, 'rU')
text = target.read()
match = re.findall(r'.*?', text)
new = open('Matches', 'w')
for i in match:
new.write(i + '\n')

Dimitar

[Tutor] Creating an object which is an extension of a dictionary
I'm attempting to create an object which can have elements which can be
referenced like a dictionary but can also have normal methods and
attributes like a conventional object but can also be referenced with key
items using d[key]
The dictionary I have is below:
UPPERCASE = "ucase"
LOWERCASE = "lcase"
DEFAULT_TYPING_SETTINGS = {"allow letters" : True,
"default case" : LOWERCASE,
"allow uppercase" : True,
"allow lowercase" : True,
"allow shift case change" : True,
"allow caps lock uppercase" : True,
"allow numbers" : True,
"allow standard numbers" : True,
"allow keypad numbers" : True,
"allow spaces" : True,
"space keys" : K_SPACE,
"allow backspace" : True,
"backspace keys" : K_BACKSPACE,
"allow newline" : False,
"newline keys" : K_RETURN,
"allow tab" : False,
"tab keys" : K_TAB,
"tab stop" : 4,
"allow punctuation" : True,
"allow standard punctuation" : True,
"allow shift punctuation" : True,
"allow number key punctuation" : True,
"allow keypad punctuation" : True,
"punctuation allowed" : None,
"punctuation disallowed" : None,
"show cursor" : False,
"allow navigation" : False,
"allow horizontal navigation" : False,
"allow vertical navigation" : False,
"allow arrow key navigation" : False,
"allow keypad navigation" : False}
I want to set an attribute for an object's typing settings which I can
change any of these individually but I also want to be able to reference
methods which can be called to perform operations such as allow all letters.
Ideally I want a typing settings object where I can get and set attributes
using for example:
typing_settings["allow uppercase"] = True
but I also want to create methods I can all using dot notation so I need
something which is a cross between a dictionary and a conventional object.
It isn't absolutely necessary but I would also like to validate when
setting the dictionary attributes such as converting necessary values to
boolean when setting and ensure the default case attribute is either UPPER
or LOWER
Thanks for any suggestions
Ian

Join the gang, any suggestions are appropriate since even when
they aren't completely correct they offer learning
opportunities. So all contributions are welcome.

The regex approach is good if the pattern is not a simple string.
And it also has the advantage that you can findall() in one operation.
The downside is that regex are notoriously hard to get right for
anything other than trivial.

You should probably use the 'with' style
with open(filename, 'rU') as target:
# code here
> # The regular expression should match every single tag and its content

You need a slash for the second tag:
match = re.findall(r'.*?', text)
> def textfind(filename):
> target = open(filename, 'rU')
> text = target.read()
> match = re.findall(r'.*?', text)

You should either close() the file after writing or use the
'with' style (which closes automatically). Otherwise if your
program terminated suddenly your data might not make it from
the buffer to the disk. The 'with' style is preferred.
with open('Matches', 'w') as new:
for m in matches:
new.write(m + '\n')
But your overall point that a regex can be used is correct,
especially if the pattern were not consistent (for example
if the tag sometimes had spaces or different cased letters).

I think __setitem__() is the one you need but the docs will clarify. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
