我正在尝试使用csv模块读取utf-8 csv文件,由于编码,我在创建python 2和3的通用代码时遇到了一些麻烦.

这是Python 2.7中的原始代码:

with open(filename, 'rb') as csvfile:
    csv_reader = csv.reader(csvfile, quotechar='\"')
    langs = next(csv_reader)[1:]
    for row in csv_reader:
        pass

但是当我用python 3运行它时,它不喜欢我没有"编码"打开文件的事实.我试过这个:

with codecs.open(filename, 'r', encoding='utf-8') as csvfile:
    csv_reader = csv.reader(csvfile, quotechar='\"')
    langs = next(csv_reader)[1:]
    for row in csv_reader:
        pass

现在python 2无法解码"for"循环中的行.那么......我该怎么做？

我搜索了一下但我找不到一个tuto使用PIL和PyPy.根据PyPy的博客,PIL得到了支持.

• 我在PYTHONPATH中安装了PIL.
• 下载后,pip制作2个.pyd文件:_imaging.pyd和_imagingmath.pyd.
• 安装完成后,我将%PYTHONPATH%/ lib/site-packages/PIL复制到我的PyPy site-packages目录.
• 当我运行我的脚本(使用PIL)时,它说它无法导入_imaging C模块.

我该怎么办？

编辑:我在Windows 7 x64(python 2.7.1 32bits)上运行
