Python在没有换行符的地方为换行符添加句号

我有一个带有文本的PDF，我使用PuMuPDF（fitz）按每页提取数据。我想为开头的句子加上句号。示例和代码如下所示：

例如：

MORE PAGE INFO 
Name of the company and some info
More info here and here 
The data above is correct. We are a registered firm, ("ABC") for this company. 
Technology etc, more sentences and a paragraph here. These sentences are much longer etc. 
Here is another Pixmap example that creates Sierpinski’s Carpet – a fractal generalizing the Cantor Set to two dimensions. Given a square carpet.

期望输出：

MORE PAGE INFO.
Name of the company and some info.
More info here and here. 
The data above is correct. We are a registered firm, ("ABC") for this company. 
Technology etc, more sentences and a paragraph here. These sentences are much longer etc. 
Here is another Pixmap example that creates Sierpinski’s Carpet – a fractal generalizing the Cantor Set to two dimensions. Given a square carpet.

当前代码：

doc  =fitz.open(myfile)
page=doc[0]
for page in doc:
    text = page.getText("text")
    text =text.replace ("\n",'.')
    print(text)

代码输出确实为短句添加了句号，但也为格式正确的句子添加了句号。我还有别的办法吗

谢谢
