如何在python 3.3.3中读取文本文件并将其存储在变量中?我正在为来自python 2.x的unicode苦苦挣扎

How do I read in a text file in python 3.3.3 and store it in a variable? I'm struggling with this unicode coming from python 2.x

推荐答案

给出此文件:

utf-8:   áèíöû

这按预期工作( IFF utf-8是您的默认编码):

with open('/tmp/unicode.txt') as f:
    variable=f.read()

print(variable)  

如果您不确定默认值是什么，最好通过使用打开:

It is better to explicitly state your intensions if you are unsure what the default is by using a keyword argument to open:

with open('/tmp/unicode.txt', encoding='utf-8') as f:
    variable=f.read()

关键字受支持的编码位于编解码器模块中.(对于Python 2，您需要使用编解码器打开来打开文件而不是Python 2的打开 BTW.)

The keyword encodings supported are in the codec module. (For Python 2, you need to use codecs open to open the file rather than Python 2's open BTW.)
