+
+
+<p>A productive approach to defining new classes is to determine what instance
+attributes each object should have and what class attributes each class should
+have. First, describe the type of each attribute and how it will be used, then
+try to implement the class's methods in terms of those attributes.</p>
+
+
+<h3 id="q1-keyboard">Q1: Keyboard</h3>
+
+
+<p><strong>Overview:</strong> A keyboard has a button for every letter of the alphabet. When a
+button is pressed, it outputs its letter by calling an <code>output</code> function (such
+as <code>print</code>). Whether that letter is uppercase or lowercase depends on how many
+times the <em>caps lock</em> key has been pressed.</p>
+
+<p><strong>First</strong>, implement the <code>Button</code> class, which takes a lowercase <code>letter</code> (a
+string) and a one-argument <code>output</code> function, such as <code>Button(&#x27;c&#x27;, print)</code>.</p>
+
+<p>The <code>press</code> method of a <code>Button</code> calls its <code>output</code> attribute (a function) on
+its <code>letter</code> attribute: either uppercase if <code>caps_lock</code> has been pressed an odd
+number of times or lowercase otherwise. The <code>press</code> method also increments
+<code>pressed</code> and returns the key that was pressed. <em>Hint</em>: <code>&#x27;hi&#x27;.upper()</code> evaluates
+to <code>&#x27;HI&#x27;</code>.</p>
+
+<p><strong>Second</strong>, implement the <code>Keyboard</code> class. A <code>Keyboard</code> has a dictionary called
+<code>keys</code> containing a <code>Button</code> (with its <code>letter</code> as its key) for each letter in
+<code>LOWERCASE_LETTERS</code>. It also has a list of the letters <code>typed</code>, which may be
+a mix of uppercase and lowercase letters.</p>
+
+<p>The <code>type</code> method takes a string <code>word</code> containing only lowercase letters. It
+invokes the <code>press</code> method of the <code>Button</code> in <code>keys</code> for each letter in <code>word</code>,
+which adds a letter (either lowercase or uppercase depending on <code>caps_lock</code>) to
+the <code>Keyboard</code>'s <code>typed</code> list.  <strong>Important:</strong> Do not use <code>upper</code> or <code>letter</code> in
+your implementation of <code>type</code>; just call <code>press</code> instead.</p>
+
+<p>Read the doctests and talk about:</p>
+
+<ul>
+  <li>Why it's possible to press a button repeatedly with <code>.press().press().press()</code>.</li>
+  <li>Why pressing a button repeatedly sometimes prints on only one line and sometimes
+  prints multiple lines.</li>
+  <li>Why <code>bored.typed</code> has 10 elements at the end.</li>
+</ul>
+
+<p><strong>Discussion Time</strong>: Before anyone types anything, have a conversation
+describing the type of each attribute and how it will be used. Start with
+<code>Button</code>: how will <code>letter</code> and <code>output</code> be used? Then discuss <code>Keyboard</code>: how
+will <code>typed</code> and <code>keys</code> be used? How will new letters be added to the list
+called <code>typed</code> each time a <code>Button</code> in <code>keys</code> is pressed? Call the staff if
+you're not sure! Once everyone understands the answers to these questions, you
+can try writing the code together.</p>
