如何在大量文本中替换性别代词？

Question

我正在写一部小说，在写到一半的时候，我决定把一个重要的主人公从男性变成女性。我编写了一些简单的Python代码，认为我可以轻松地更改该特定字符的代词，但它意外地更改了所有字符的代词。以下是小说中的一些示例文本：

example_text = "John walked to the market. He was tired, but decided to leg it anyway, he needed the exercise! He met Joe along the way. Joe was a tall man and walked fast, during his heyday, he was an impressive athlete."

我希望将Joe（男性）更改为Jane（女性），并编写了以下简单代码：

example_text = example_text.replace(" he ", " she ")
example_text = example_text.replace(" He ", " She ")
example_text = example_text.replace(" his ", " her ")
example_text = example_text.replace(" man ", " woman ")
example_text = example_text.replace("Joe", "Jane")

但是上面的代码将乔和约翰的代词都改为女性。我现在意识到我必须使用NLP来实现这一点，但是否有一个模块或算法来实现这一点
