Easy Problem

Hello,
    I have 2 plain text documents that have uneven spacing. I need to make these single spaced between lines and between words. Basically I need to get them to be equal character length after I abridge the uneven spacing. In Python there is probably one simple command for this for a text file? How do I do this?
E.G.: Hi          how are you?
Fixed: Hi how are you?
        Thanks,
                Ishan

'Hi how are you?'

there are directions on how to remove yourself from the list at the bottom of every message that the list sends out.

I think "non standard HTML package" pretty much hits the nail on the head.

That, again, is questionable. The task at hand was to "update HTML pages",
in which case it is quite useful to have them fixed up into standard
compliant HTML before working on them. BeautifulSoup will not do that for
you. Instead, it will leave you with whatever tag soup you had at the
beginning, so that you will end up sending out broken HTML again. I
wouldn't call that "well behaved" at all.

May I suggest,

to slightly tweak the signature of the ML with something like:

---
Tutor mailing list  -  tutor <at> python.org
Configuration options (including unsubscribing):
http://mail.python.org/mailman/listinfo/tutor
---

so that the less tech-savvy among the subscribers get a better hint on
how to manage by themselves?

Mac.

Good idea, see below (I hope)

txt.strip() only remove leading and trailing white space so does
nothing in your example. However it works because txt.split() removes
the excessive white space between the text.

>>> txt
'Hi          how are you?'
>>> ' '.join(txt.split())
'Hi how are you?'

I don't know what you mean by "equal character length" here.

Another way to do this is with regular expressions, for example
In [1]: import re

In [2]: txt = "Hi          how are you?"

In [4]: txt = re.sub(r'  +', ' ', txt)

In [5]: txt
Out[5]: 'Hi how are you?'

You can also replace multiple newlines with single newlines. The
details of that will depend on the line endings in your text; assuming
\n for newline then you could use
  txt = re.sub(r'\n\n+', '\n', txt)
to remove extra newlines.

The split() method won't distinguish between spaces and newlines so
you have to apply it one line at a time. The re.sub() method can work
on the entire text at once.

Tracking variable changes in a different application

Hi again,

The question might be a tad confusing, but what I want to ask is, if it's possible to track if and when a variable in an application has changed, and then grab the new content of that variable?
I have my product inventory database application which is attached to another bigger application. Some of the data I need comes from that bigger application, like for instance Consumer information (not handled by the application that I'm working on). So, if the address of a consumer is changed, how my application track the changes without having to do something like:

        class Consumer(objectOfSomething):
                  -----
                  -----
                  def updateConsumerInfo(newAddress):
                          newAddress = newAddress
                          inventory.updateConsumerInfo(newAddress)        #<<<not updating from here

instead only read from class:
        class Consumer(objectOfSomething):
                  -----
                  -----
                  def updateConsumerInfo(newAddress):
                          newAddress = newAddress

and track the change of newAddress from the function updateConsumerInfo in class Consumer.

Is this possible to do? (if my question even make sense)

Thanks for any responses!

Best,
Krissy
