在一组文件中查找非ascii字符 [英] Finding non ascii characters in a set of files

问题描述

我正在将我的程序更新为Python 2.5，但我一直遇到

编码问题。在我的脚本的任何一个开头都没有定义生态。我想要做的是扫描目录并列出其中包含非ascii字符的所有

文件。我怎么会这样做？
这样做？


谢谢，

Hi,

I''m updating my program to Python 2.5, but I keep running into
encoding problems. I have no ecodings defined at the start of any of
my scripts. What I''d like to do is scan a directory and list all the
files in it that contain a non ascii character. How would I go about
doing this?

Thanks,

Barry.

这样的事情怎么样：

content = open（ ''file.py''）。read（）

试试：

content.encode（''ascii''）

除了UnicodeDecodeError ：

print" file.py包含非ascii字符"

How about something like this:
content = open(''file.py'').read()
try:
content.encode(''ascii'')
except UnicodeDecodeError:
print "file.py contains non-ascii characters"

下一个问题是非文本文件将包含非-ASCII

个字符（字节）。另一个''问题'是OP没有说文件有多大
，所以.read（）可能是个问题。

The next problem will be that non-text files will contain non-ASCII
characters (bytes). The other ''issue'' is that OP didn''t say how large
the files were, so .read() might be a problem.
