if x in self.a:
return self.a[x]

1,129,380 | 1,129,381 | Chained Method Calls in Python with dict | <p>I needed to flatten a dictionary today. Meaning I wanted:</p>
<pre><code>{'_id': 0, 'sub': {'a': 1, 'b':2}}
</code></pre>
<p>to become:</p>
<pre><code>{'_id': 0, 'a':1, 'b':2}
</code></pre>
<p>So I thought I could be clever and pull off the following one-liner.</p>
<h2>One-liner:</h2>
<pre><code>x = dict(_id=0, sub=dict(a=1, b=2))
y = x.pop('sub').update(x) # incorrect result
</code></pre>
<p>This results in <code>y = None</code>.</p>
<p>So I obviously resorted to:</p>
<h2>Multi-Step:</h2>
<pre><code>x = dict(_id=0, sub=dict(a=1, b=2))
y = x.pop('sub')
y.update(x) # correct result
</code></pre>
<p>Setting "good expressive coding practices" asside for a moment, I would like to understand why the <strong>One-liner</strong> approach above yields <code>None</code>. I would have thought that x.pop('sub') would have resulted in a temporary dict on a stack somewhere and the original x dict would be immediately updated. Then the stack object would receive the next method in the chain which is the update. This obviously does not seem to be the case.</p>
<p>For the communities better understanding (and clearly mine) - how does python resolve the one-liner and result in <strong>None</strong>? </p>

This must be an easy one but I'm really at a loss... The following code draws a rectangle with a linear gradient going from left to right, from white to black, </p>

paint.setShader(shader);
canvas.drawRect(new RectF(x1, y1, x2, y2), paint);
Ok, fine. Now what I'd like to do is to change this gradient into a <strong>horizontal</strong> one, so that the color goes from white to black, from top to bottom. What I tried to do is to add:</p>
<pre><code>Matrix trans = new Matrix();
</code></pre>
<p>trans.setRotate(90);
shader.setLocalMatrix(trans);
but instead the gradient goes at a funny angel, or there is just a single color... I also tried to play with the coordinates of the gradient in all sorts of way (thinking that maybe they should be transformed) to no avail. What am I missing?</p>

<p>and if I then don't add any Category to the Intent object:</p>
<pre><code> ...
Intent intent = new Intent(Intent.ACTION_INSERT);
startActivity(intent);
...
</code></pre>
<p>That works. However, as soon as I define any other category than <code>android.intent.category.DEFAULT</code> I am only getting <code>ActivityNotFoundException</code>s. E.g. if I specify:</p>
<pre><code> ...
<activity
android:name="mmmo.android.test.ItemDetails"
<intent-filter>
<action android:name="android.intent.action.INSERT" />
<category android:name="foo.bar" />

<p>and then try to start that Activity using:</p>
<pre><code> ...
Intent intent = new Intent(Intent.ACTION_INSERT);
intent.addCategory("foo.bar");
startActivity(intent);
...
</code></pre>
<p>this does not work. The doc reads "... every category in the Intent object must match a category in the filter. ...". The category name I add to the Intent matches the category I specified in the filter. So why does this not match up and just throws an exception???</p>
