Revision 2. </p> <p>This script shows how to upload epub files in Library Genesys (libgen) automatically by using Tor. Please note that only copyright free epubs should be used (such as those present in <a href="https://www.gutenberg.org/" rel="nofollow">https://www.gutenberg.org/</a>). It will also check if MD5 hash is present before uploading. This is provided for python educative purposes only : it shows how to use a Tor proxy, Mechanize (for uploading and form processing), Hashlib for MD5 calculation, Filemagic for mimetype detecting and BeautifulSoup for response analyzing, all together.</p>

Revision 7. </p> <p>This recipe addresses the problems encountered when building robust tests for Tk menus. The software under test is a simple window with two menu items that each invoke a one button dialog box. All user visible text is imported from an external config.ini file. This scenario can lead to fragile test code because of the way TK's invoke(index) command has been implemented. (Tcl8.6.3/Tk8.6.3.)</p>

<p style="color: grey"> Python recipe 552745 by <a href="/recipes/users/4093058/">Ronald Longo</a> (<a href="/recipes/tags/algorithms/">algorithms</a>). Revision 6. </p> <p>If you're writing some Tkinter software and you're sizing something in inches or centimeters and tkinter only gives you feedback in pixel distances then you may need a way to get back to your prefered units of measure. I recently found myself in this situation. There's nothing fancy about the set of functions here, it's more about the little known winfo_fpixels() function. Once you know about this everything else is a piece of cake. These functions are simple, but convenient.</p>

Record the indices of the elements in target_array that are within tolerance, tol, of their closest match. Also record the indices of the elements in target_array that are outside tolerance, tol, of their match. For example, given an array of observations with irregular observation times along with an array of times of interest, this routine can be used to find those observations that are closest to the times of interest that are within a given time tolerance. </code></pre>

<p style="color: grey"> Python recipe 266468 by <a href="/recipes/users/1590094/">Ivo Timmermans</a> (<a href="/recipes/tags/oop/">oop</a>). Revision 2. </p> <p>The point is that python doesn't have a notion of “abstract methods.” Abstract methods are part of an base class that defines an interface, without any code. Abstract methods can't be called directly, because they don't contain any code in their definition.</p> <p>In the definition of the base class, you may want to include a specific method that is part of the interface, but the specific implementation is still unknown. A popular example seems to be the drawing of a point or a line in a graphical application.</p> <p>The classes Point and Line share several implementation details, but differ on other. In particular, the way they are drawn is completely different (you will want to optimize the drawing of a line). Suppose these two classes are derived from the same class, Object. It is possible to separate the implementation of the method draw of these two classes, while draw can still be called from the base class Object.</p>

<p style="color: grey"> Python recipe 120687 by <a href="/recipes/users/235719/">Henk Punt</a> . </p> <p>The following code implements a splash screen as typically found in windows applications. Using only API's available from win32gui, win32api and win32con, it avoids dependancy on MFC (wrapped by win32ui). This way the 600kb or so win32ui.pyd extension DLL is not needed when freezing your app with py2exe. Another 80kb could be squeezed out by not using win32con but to define the necessary constants directly in the code itself.</p>

I am now using a modified version mainly for error numbers instead of an Error class. It's just very nice not to worry about values.</p>
