 Python automatically assigns the value of <code class="docutils literal notranslate"><span class="pre">key</span></code> to the name of the next key in the dictionary. Inside of the <code class="docutils literal notranslate"><span class="pre">for</span></code> loop the code uses <code class="docutils literal notranslate"><span class="pre">key</span></code> to access the value of each key of the dictionary. This is a common way for iterating over a dictionary, but it is not the preferred way in Python.</p>
