<p>i.e. I want to strip out all words that have a prefix of # and @. (And yes, im inspecting tweets)</p>
<p>I am new to python, and I would be ok doing this on single words, but not sure on the best way to achieve this on a string that contains multiple words.</p>
<p>My first thoughts would be to use replace, but that would just strip out the actual @ and # symbols. <strong>Looking for the best way to strip out any word that has a prefix of # or @.</strong></p>
<p>-EDIT-
Not sure if it this invalidates the answers give, but for acceptance, I also need to strip out where multiple words contain a prefix of # or $. e.g. hello #hiya #ello</p>

<p>When I logged in, my receivers starting activity B properly, but unfortunately when I pressed the back button, application turning back to activity A. </p>
<p>I suppose it's about <code>launchMode</code> and as I said, Twitter needs that option. What am I doing wrong? Any help or suggestion (maybe about Twitter) would be great.</p>

This plugin would require several views, images, an activity and a parser for CharSequences... Ideally, this plugin would be downloadable from the Android Market. </p>
<p>I understand how to create a library, but that would need to be included in the application.</p>
<p>I understand how to create an app as a service and just call it via intents, but I need direct access to objects and code that is neither parceable nor serializable.</p>
<p>What I have been looking at is <a href="http://code.google.com/p/eyes-free/">eyes-free TTS</a>. With their implementation, the developer includes a small TTS_library_stub.jar file in their app, which looks like it defines a lot of the necessary classes/objects.</p>
<p>So my question is, how would I go about building something like this and generating this "stub" .jar file, which would be included in my app? I've been trying to work my way through the TTS code, but it's a massive codebase, and I'm having trouble finding what I'm looking for.</p>

3,181,282 | 3,181,283 | What is your strategy to avoid dynamic typing errors in Python (NoneType has no attribute x)? | <p>Python is one of my favorite languages, but I really have a love/hate relationship with it's dynamicness. Apart from the advantages, it often results in me forgetting to check a type, trying to call an attribute and getting the NoneType (or any other) has no attribute x error. A lot of them are pretty harmless but if not handled correctly they can bring down your entire app/process/etc. Over time I got better predicting where these could pop up and adding explicit type checking, but because I'm only human I miss one occasionally and then some end-user finds it.</p>
<p>So I'm interested in your strategy to avoid these. Do you use type-checking decorators? Maybe special object wrappers? Please share...</p>
