按照你说的进行了调整，报错如下： Traceback (most recent call last): File "/temp/py/app-07240001.py", line 16, in display_yaml TypeError: Object of type 'Undefined' is not JSON serializable

这个错误通常是由于在模板中使用了未定义的变量引起的。请确保在传递给模板的上下文变量中包含了正确的数据。在这种情况下，可能是因为`data`变量没有正确传递给了模板。你可以在调用`render_template`函数时，将解析后的YAML数据作为参数传递给模板。请使用以下代码进行更新： ```python @app.route('/') def display_yaml(): with open('your_file.yml', 'r') as file: data = yaml.safe_load(file) return render_template('index.html', data=data) ``` 请确保将`your_file.yml`替换为实际的YAML文件路径。然后，在`index.html`模板文件中，你可以使用Jinja2语法来展示YAML数据。下面是一个示例： ```html <!DOCTYPE html> <html> <head> <title>Display YAML</title> </head> <body> <h1>YAML Data:</h1> <pre>{{ data }}</pre> </body> </html> ``` 请确保保存并重新运行你的应用，然后刷新浏览器查看结果。如果问题仍然存在，请提供完整的错误堆栈信息以供参考。

这个错误通常是由于模板中使用了未定义的变量引起的。在这种情况下，错误发生在`{{ data|tojson|safe }}`这一行，说明`data`变量没有正确传递给模板。请确保在调用`render_template`函数时，将`data`变量作为参数传递给模板。你可以尝试将`data`变量传递给模板的方式更改为以下代码： ```python @app.route('/') def display_yaml(): with open('your_file.yml', 'r') as file: data = file.read() highlighted_data = highlight(data, YamlLexer(), HtmlFormatter()) css = HtmlFormatter().get_style_defs('.highlight') return render_template('index.html', data=data, highlighted_data=highlighted_data, css=css) ``` 然后，在`index.html`模板文件中，你需要将`data`变量传递给JavaScript部分，可以将以下代码添加到JavaScript部分： ```html <script> var originalData = {{ data|tojson|safe }}; // ... </script> ``` 这样，`originalData`变量就能正确地接收来自Python代码的数据。请确保保存并重新运行你的应用，并刷新浏览器查看结果。如果问题仍然存在，请提供完整的错误堆栈信息以供参考。

Traceback (most recent call last): File "C:\Users\Think\AppData\Local\Temp\codemao-lRrXMT/temp.py", line 24, in <module> ciphertext += letters[a + 6:a + 7] TypeError: must be str, not list

这个错误是因为你在代码中使用了列表而不是字符串。请检查你的代码并确保你在操作字符串时使用了字符串的变量类型。另外，你可以在代码中使用join方法将列表转换为字符串。例如，如果你有一个名为letters的列表，你可以使用以下代码将其转换为字符串： ``` ciphertext = ''.join(letters[a + 6:a + 7]) ``` 这将把letters列表中从a+6到a+7的字符连接起来，形成一个字符串。
