ImportError :没有名为difflib_data的模块

Question

我正在使用windows 7中的python3.4，尝试比较两个文本文件，并希望使用difflib报告它们之间的差异。下面是使用的代码m：

import difflib
from difflib_data import *

with open("s1.txt") as f, open("s2.txt") as g:
    flines = f.readlines()
    glines = g.readlines()

d = difflib.Differ()
diff = d.compare(flines, glines)
print("\n".join(diff))

回溯:从difflib_data导入* ImportError:没有名为“difflib_data”的模块

如何删除此error....thanks

从以下职位来看，这似乎是PyMOTW教程提供的示例数据。

我假设作者希望您将测试数据源复制并粘贴到工作dir中名为difflib_data.py的新文件中。

将下列行复制到difflib_data.py中

text1 = """Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Integereu lacus accumsan arcu fermentum euismod. Donec pulvinar porttitortellus. Aliquam venenatis. Donec facilisis pharetra tortor. In necmauris eget magna consequat convallis. Nam sed sem vitae odiopellentesque interdum. Sed consequat viverra nisl. Suspendisse arcumetus, blandit quis, rhoncus ac, pharetra eget, velit. Maurisurna. Morbi nonummy molestie orci. Praesent nisi elit, fringilla ac,suscipit non, tristique vel, mauris. Curabitur vel lorem id nisl portaadipiscing. Suspendisse eu lectus. In nunc. Duis vulputate tristiqueenim. Donec quis lectus a justo imperdiet tempus."""

text1_lines = text1.splitlines()

text2 = """Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Integereu lacus accumsan arcu fermentum euismod. Donec pulvinar porttitortellus. Aliquam venenatis. Donec facilisis pharetra tortor. In necmauris eget magna consequat convallis. Nam sed sem vitae odiopellentesque interdum. Sed consequat viverra nisl.

text2_lines = text2.splitlines()
