Python Flask和Jinja-从数据库获取文本

Question

I'm using Python with Flask and Jinja2. I am getting some text from my database (SQLITE 3) and in the database it is displayed properly with line breaks. However when I display this text on the website it all displays on one line.

It should be displayed like this:

Hello How are you?

but it's appearing as:

Hello How are you?

Answer 1

In python strings, newlines are signified via the \\n character, in HTML you need <br /> for that. So you need to add this to your string:

my_string = my_string.replace("\n", "<br />)
