js变量的正则表达式以分号结尾

Question

I am trying to find and extract an assignment of a property of the product_image object from Javascript code, extracted with BeautifulSoup. I have tried following

re.findall(r"product_images\['top_lg'] = .*;", txt)  

Unfortunately it does not extract anything from my text below.

 product_images['top_lg'] = {
                "tn": '//image.test.com/media/cache/04/0a/040a1e61f5edc387d8c8e40d3ea0e0ca.jpg',
                "md": '//image.test.com/media/cache/b7/f3/b7f3cb1da267d7e8ac0412bdc522c862.jpg',
                "lg": '//image.test.com/media/shape_images/011f7f24ae4cbbef191cff1a711df9e1_a3c9ca71b7d85d87085955f8d1c4bfc3_0_.jpg',
                "alt": 'test ',
                "data-zoomable": 'True',
                "text_line": 'teest'
            };

The scripts that I am parsing are taken from https://www.brilliantearth.com/Petite-Twisted-Vine-Diamond-Ring-White-Gold-BE1D54-3821855/

If, like me, you find regex flags confusing and hard to remember, use "not semicolon" expressions instead of dot

re.findall(r"product_images\\['top_lg'] = [^;]*;", txt)

Note . Otherwise you can add a flag as Thierry suggests, though you would need also add a 'non-gready modifier' ? after * to indicate that you are interested in the first semicolon rather that the last.
