<p>有些版本的 Python 直譯器支援當前輸入內容的編輯和歷史記錄的替換 (history substitution)，類似在 Korn shell 和 GNU Bash shell 中的功能。這個功能是用 <a class="reference external" href="https://tiswww.case.edu/php/chet/readline/rltop.html">GNU Readline</a> 函式庫來實作，它支援多種編輯的風格。這個函式庫有它自己的說明文件，在這裡我們就不重複了。</p>
<section id="tab-completion-and-history-editing">
<span id="tut-keybindings"></span><h2><span class="section-number">14.1. </span>Tab 鍵自動完成 (Tab Completion) 和歷史記錄編輯 (History Editing)<a class="headerlink" href="#tab-completion-and-history-editing" title="連結到這個標頭">¶</a></h2>
<p>在直譯器啟動的時候，變數和模組名稱的自動完成功能會被<a class="reference internal" href="../library/site.html#rlcompleter-config"><span class="std std-ref">自動啟用</span></a>，所以可以用 <kbd class="kbd docutils literal notranslate">Tab</kbd> 鍵來呼叫自動完成函式；它會查看 Python 的陳述式名稱、當前區域變數名稱和可用模組名稱。對於像是 <code class="docutils literal notranslate"><span class="pre">string.a</span></code> 的點分隔運算式 (dotted expression)，它會對最後一個 <code class="docutils literal notranslate"><span class="pre">'.'</span></code> 之前的運算式求值，然後根據求值結果物件的屬性，給予自動完成的建議。請注意，如果一個物件有 <a class="reference internal" href="../reference/datamodel.html#object.__getattr__" title="object.__getattr__"><code class="xref py py-meth docutils literal notranslate"><span class="pre">__getattr__()</span></code></a> method（方法），同時又是該運算式的一部份，這樣可能會執行應用程式自定義的程式碼。預設設定也會把你的指令歷史記錄儲存在你的使用者資料夾內，一個名為 <code class="file docutils literal notranslate"><span class="pre">.python_history</span></code> 的檔案中。在下一次啟動互動式直譯器時，這些歷史記錄依然可以被使用。</p>
</section>
<section id="alternatives-to-the-interactive-interpreter">
<span id="tut-commentary"></span><h2><span class="section-number">14.2. </span>互動式直譯器的替代方案<a class="headerlink" href="#alternatives-to-the-interactive-interpreter" title="連結到這個標頭">¶</a></h2>
<p>與早期版本的直譯器相比，上述功能的出現的確是一個巨大的進步；但還是有一些願望沒有被實現：如果能在每次換行時給予適當的縮排建議（剖析器 (parser) 知道下一行是否需要縮排標記 (indent token)），那就更棒了。自動完成機制可能會使用直譯器的符號表。若有一個命令能夠檢查（或甚至建議）括號、引號和其他符號的匹配，那也會很有用。</p>
<p>有一個功能增強的互動式直譯器替代方案，已經存在一段時間，稱為 <a class="reference external" href="https://ipython.org/">IPython</a>，它具有 Tab 鍵自動完成、物件探索和進階歷史記錄管理等特色。它也可以完全客製化並被嵌入到其他應用程式中。另一個類似的增強型互動式環境，稱為 <a class="reference external" href="https://bpython-interpreter.org/">bpython</a>。</p>
