Python CSV DictReader，带有UTF-8数据 [英] Python CSV DictReader with UTF-8 data

问题描述

AFAIK，Python（v2.6）csv模块默认情况下不能处理unicode数据，是否正确？在Python文档中，有关于如何从UTF-8编码文件读取的示例。但此示例仅返回CSV列作为列表。
我想按照名称访问行列，因为它是由 csv.DictReader ，但使用UTF-8编码的CSV输入文件。

AFAIK, the Python (v2.6) csv module can't handle unicode data by default, correct? In the Python docs there's an example on how to read from a UTF-8 encoded file. But this example only returns the CSV rows as a list. I'd like to access the row columns by name as it is done by csv.DictReader but with UTF-8 encoded CSV input file.

任何人都可以告诉我如何以有效的方式做到这一点？

Can anyone tell me how to do this in an efficient way? I will have to process CSV files in 100's of MByte in size.

推荐答案

实际上，我自己想出了一个答案（对不起用于回复我自己的问题）：

Actually, I came up with an answer myself (sorry for replying to my own question):

def UnicodeDictReader(utf8_data, **kwargs):
    csv_reader = csv.DictReader(utf8_data, **kwargs)
    for row in csv_reader:
        yield {unicode(key, 'utf-8'):unicode(value, 'utf-8') for key, value in row.iteritems()}
