5,478,939 | 5,478,940 | How To Call A Function With Proper 'Arguments' | <p>I have a function that takes 2 returned variables from another function to write them with a little bit more padding text to an external text file.</p>
<p>The code that I am using to write to the text file is below but it is being called automatically at runtime with the <code>if</code> statement at the bottom of the program</p>
<pre><code>def function1()
# Some code
def function2()
# Some code
return startNode
return endNode
def function3(var)
# Some code
return differentVariable
def createFile(startNode, endNode):
outputFile = open('filename.txt','w') # Create and open text file
start = chr(startNode +65) # Converts the int to its respective Char
end = chr(endNode +65) # Converts the int to its respective Char
outputFile.write('Route Start Node: ' + start + '\n') # e.g Route Start Node: B
outputFile.write('Route end node: ' + end + '\n') # e.g Route End Node: F
outputFile.write('Route: ' + Path + '\n') # e.g Path: B,A,D,F
outputFile.write('Total distance: ' + Distance) # e.g Total Distance: 4
outputFile.close # Close file
if __name__ == "__main__":
function1()
function3(function2())
createFile( # Don't Know What Goes Here )
</code></pre>
<p>At the moment I am only able to run this function by manually calling it and entering <code>createFile(1,5)</code> where the 1 is the startNode value and the 5 is the endNode value</p>
<p>But if I am to put <code>createFile(startNode, endNode)</code> in the <code>if</code> statement to call the function, it tells me <code>NameError: name 'startNode' is not defined</code> and then it would obviously give me the same error for endNode too</p>
<p>How do I call that function properly without having to enter the values manually because they can change depending on what the startNode and endNode values are at the start of the program?</p>

5,857,550 | 5,857,551 | Can an unescaped apostrophe in a literal defined in strings.xml cause my app to crash? | <p>Google's official documentation mentions:</p>
<p>Escaping apostrophes and quotes</p>
<p>If you have an apostrophe or a quote in your string, you must either escape it or enclose the whole string in the other type of enclosing quotes. For example, here are some stings that do and don't work:</p>
<pre><code><string name="good_example">"This'll work"</string>
<string name="good_example_2">This\'ll also work</string>
<string name="bad_example">This doesn't work</string>
<string name="bad_example_2">XML encodings don&apos;t work</string>
</code></pre>
<p>My question is: Would unescaped quotes cause the application to crash or would it just have no effect and the quotes won't appear in the app UI? Would it crash on specific Android versions? I ask this because if I don't escape this symbol, Eclipse SDK gives me compilation errors but I came across a third-party app code which does not escape these characters, it crashes randomly and I'd like to confirm that this is/ is not one of the possible reasons for the crash.</p>

<pre><code><div id="BodyField">
<div class="video-field-new"></div>
</div>
</code></pre>
<p>So I would like the DIV with "video-field-new" to hide when user clicks inside of #BodyField.</p>
<p><strong>Background</strong>: I have a small banner that lays over a video in the corner when the video is new, but I do not want it to block the video player when the user plays the video. So ideally when the user clicks to play the video, which is inside the #BodyField then the banner will hide.</p>

<p>how can I add a certain number to each cell according to its position in the lists

so lets say the second cell on the third list will be </p>

<p>Everything seems to work fine in the emulator, but I don't know how to simulate turning it.
So I tried running the app on my pandigital (white model - lowest of the low it seems), and each time I turn the Android, it freezes up. At least the UI freezes up, I believe the debug messages are still printing.
This is a home project, I don't have other devices to try it on.</p>
<p>Sorry for being so vague, it's an issue I have been a bit neglecting, trying to work on more interesting issues first, but it's an issue that is bothering me in the back of my mind.</p>
<p>Anyway, I have an Activity that starts up a thread, and creates a class which responds to various events, it implements: MainInterface and SurfaceHolder.Callback. Is there something else I should be handling? possibly?
Is there some specific call I get when the tablet is turned? I'd like to put a debug message in there.</p>
