试图在同一html屏幕上显示用户输入的输出

Question

我相信这并不困难，我只是刚接触Django，非常感谢您的帮助

我一直试图将两个输入（“句子”变量和“单词”变量）作为字符域。然后获取这两个输入并使用它们创建新的输出。我可以在控制台上打印，但不能在html页面上显示

多谢各位。 这是我得到的

    <div class="main">
        <div class="container">
            <div class="row">
                <form class="content" method="post">
                    {% csrf_token %}
                    {{ form }}
                    {% if output %}
                        <h3>{{ output }}</h3>
                    {% endif %}
                    <input type="submit" name="submit_cmd" value=Run />
                </form>
            </div>
        </div>
    </div>

您正在创建output变量，但从不将其附加到返回模板的上下文dict

return render(request, 'pk_app/form.html', {'form': form, 'output': output})

另外：您确定它属于HTML表单元素中的吗
