<p style="color: grey"> Python recipe 578672 by <a href="/recipes/users/4187940/">Rutger Saalmink</a> (<a href="/recipes/tags/chronological/">chronological</a>, <a href="/recipes/tags/exif/">exif</a>, <a href="/recipes/tags/image/">image</a>, <a href="/recipes/tags/order/">order</a>, <a href="/recipes/tags/photo/">photo</a>, <a href="/recipes/tags/picture/">picture</a>). Revision 3. </p> <p>On some occasions/events, pictures will be taken by different camera's, mobile phones, etc. In order to sort these photos chronologically, it does not suffice using the file's date modified/created set by the OS. The following script obtains, from multiple sources, the pictures' taken date stored in the accompanying Exif data and outputs them all chronologically in a single directory.</p>

Works fine.</p>

<p style="color: grey"> Python recipe 577748 by <a href="/recipes/users/4172944/">Steven D'Aprano</a> (<a href="/recipes/tags/c3/">c3</a>, <a href="/recipes/tags/classes/">classes</a>, <a href="/recipes/tags/method/">method</a>, <a href="/recipes/tags/mro/">mro</a>, <a href="/recipes/tags/order/">order</a>, <a href="/recipes/tags/resolution/">resolution</a>). </p> <p>This function allows you to calculate the Method Resolution Order (MRO, or sometimes linearization) of a class or base classes. This is the so-called "C3" algorithm, as used by Python (new-style classes, from version 2.3 and higher). The MRO is the order of base classes that Python uses to search for methods and attributes. For single inheritance, the MRO is obvious and straight-forward and not very exciting, but for multiple inheritance it's not always obvious what the MRO should be.</p>
