如何在基本 HTML 页面上使用 Python 列出单词的段落
How to list a word's paragrams using Python on a basic HTML page
我正在使用 Flask 框架 创建一个简单的 python 网络应用程序来列出单词（段落）中一个字母或一系列字母的变化。控制台（IntelliJ 代码编辑器）成功打印出段落，但 我无法在无序 HTML 列表的 HTML 页面上打印 them/list 它们 - 请参阅以下 HTML 页面的屏幕截图
我尝试了 (''.join) 和 (','.join(str(e) for e in paragram_list)) 方法，但它们对我不起作用，如下面的代码所示。请看最后return声明 (return "There are " + str(num_of_paragrams) + " Paragrams for " + "''" + str(input_word) + "'\n'" +
" ... 在这里，我想要字符串格式或列表的格式：" + str(paragram_list[paragram]) +
" ----> 这仅显示一个更改 ----> " + str(''.join(values[paragram])))
我的代码编辑器的控制台打印了下面的行，我希望在 HTML
上打印同样的内容
这里是abc这个词的段落列表
