我的特征字典看起来像这样

{
"1": {
        "Port  hw_addr": "[62, 74, 73, 133, 83, 75]",

    "OFPC_TABLE_STATS": true, 
    "buffer_size": "256", 
    "datapath_id": true
}

我无法将此字典写入 HTML 文件。对于如何解决这个问题，有任何的建议吗？

  report.write(value)
TypeError: expected a character buffer object

我认为问题是因为字典是嵌套的，我无法将其写入 HTML 文件

您正在尝试仅迭代值，而不是键值对。改用iteritems()：

for key,value in flow_stats.iteritems():
    print key
    print value

接下来，当将整数（或其他任何非字符串）写入文件时，首先将它们转换为字符串：

for key,value in flow_stats.iteritems():
    report.write(key)
    report.write(str(value))

但是使用字符串格式会让你的任务更容易：

for key,value in flow_stats.iteritems():
    report.write('<div>{}</div><div>{}</div>\n'.format(key, value))

as 字符串格式允许您添加静态字符串并定义如何将值转换为字符串。
