python - 在 Python 中生成文本修订历史的 View

Question

我有一段文本的两个版本，我想生成其修订版的 HTML View ，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:

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.

版本 2:

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.

期望的输出:

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. He is American.

使用 diff 命令不起作用，因为它告诉我哪些行不同，但没有告诉我哪些列/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 中有一个很好的 diff 实现。
