python - 在 Python 中生成文本修订历史的视图

Question

我有一段文本的两个版本，我想生成其修订版的 HTML 视图，类似于 Google Docs 或 Stack Overflow 显示的内容。我需要在 Python 中执行此操作。我不知道这种技术叫什么，但我假设它有一个名字，希望有一个 Python 库可以做到这一点。

版本 1：

威廉亨利“比尔”盖茨三世（生于 1955 年 10 月 28 日）[2] 是一位美国商业巨头、慈善家和微软董事长[3]，微软是他与保罗艾伦共同创立的软件公司。

版本 2：

威廉亨利“比尔”盖茨三世（生于 1955 年 10 月 28 日）[2] 是一位商业巨头、慈善家和微软董事长[3]，微软是他与保罗艾伦共同创立的软件公司。他是美国人。

所需的输出：

威廉亨利“比尔”盖茨三世（生于 1955 年 10 月 28 日）[2] 是一位美国商业巨头、慈善家和微软董事长[3]，微软是他与保罗艾伦共同创立的软件公司。 他是美国人。

使用 diff 命令不起作用，因为它告诉我哪些行不同，但不告诉我哪些列/单词不同。

$ echo 'William Henry "Bill" Gates III (born October 28, 1955)[2] is an American business magnate, philanthropist, and chairman[3] of Microsoft, the software company he founded with Paul Allen.' > oldfile
$ echo 'William Henry "Bill" Gates III (born October 28, 1955)[2] is a business magnate, philanthropist, and chairman[3] of Microsoft, the software company he founded with Paul Allen.  He is American.' > newfile
$ diff -u oldfile newfile

Answer 1

Google Diff Merge Patch在纯 python 中有一个非常好的 diff 实现。

Answer 2

您可以使用wdiff。我不知道是否有 Python 实现：

$ wdiff oldfile newfile
William Henry "Bill" Gates III (born October 28, 1955)[2] is [-an American-] {+a+} business magnate, philanthropist, and chairman[3] of Microsoft, the software company he founded with Paul Allen.  {+He is American.+}

Answer 3

difflib模块可能有助于解决这个问题。
