features = get_featuresreply(features_reply)
with open('index1.html', 'w') as report:
    report.write('<html>')
    report.write('<body>')

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

我的功能字典看起来像这样

我无法将此dict写入HTML文件。有关如何解决此问题的任何建议吗？

  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

Answer 1

您正试图迭代只是值，而不是键值对。请改用iteritems()：

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

接下来，当将整数（或其他任何不是字符串）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string formatting会让您的任务变得更加容易：

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

因为字符串格式化允许您添加静态字符串并定义值如何转换为字符串。
