Question

我目前正在努力解决这个错误试图告诉我的问题。我无法判断它是指我输入的一些数据，还是它是否是我创建的数据字典的引用。我甚至很难制定一个问题，这对我来说太困惑了。

这是我的代码，我实际上从这个问题的第一个答案中偷了它 - ＆gt; How to import CSV/TSV data to Couch DB?。我的困难是试图找到文档以确保我没有在我的方面做错任何事。如果有人知道我在哪里可以找到couchdbkit文档，那就太好了！他们的官方网站已关闭。

存在问题：

reader = DictReader(open(fname, 'rU'), dialect = 'excel')

尝试添加UTF-8编码：

reader = DictReader(open(fname, 'rU'),encoding='utf-8', dialect = 'excel')

不理解Python中
