<h3>24.6.3.2. IDLE-console differences<a class="headerlink" href="#idle-console-differences" title="Permalink to this headline">¶</a></h3>
<p>As much as possible, the result of executing Python code with IDLE is the
same as executing the same code in a console window. However, the different
-interface and operation occasionally affects results.</p>
-<p>For instance, IDLE normally executes user code in a separate process from
-the IDLE GUI itself. The IDLE versions of sys.stdin, .stdout, and .stderr in the
-execution process get input from and send output to the GUI process,
-which keeps control of the keyboard and screen. This is normally transparent,
-but code that access these object will see different attribute values.
-Also, functions that directly access the keyboard and screen will not work.</p>
+interface and operation occasionally affects visible results. For instance,
+<code class="docutils literal"><span class="pre">sys.modules</span></code> starts with more entries.</p>
+<p>IDLE also replaces <code class="docutils literal"><span class="pre">sys.stdin</span></code>, <code class="docutils literal"><span class="pre">sys.stdout</span></code>, and <code class="docutils literal"><span class="pre">sys.stderr</span></code> with
+objects that get input from and send output to the Shell window.
+When this window has the focus, it controls the keyboard and screen.
+This is normally transparent, but functions that directly access the keyboard
+and screen will not work. If <code class="docutils literal"><span class="pre">sys</span></code> is reset with <code class="docutils literal"><span class="pre">reload(sys)</span></code>,
+IDLE’s changes are lost and things like <code class="docutils literal"><span class="pre">input</span></code>, <code class="docutils literal"><span class="pre">raw_input</span></code>, and
+<code class="docutils literal"><span class="pre">print</span></code> will not work correctly.</p>
<p>With IDLE’s Shell, one enters, edits, and recalls complete statements.
Some consoles only work with a single physical line at a time.</p>
