Replace \n with <br />

I'm parsing text from file with Python. I have to replace all newlines (\n) with
cause this text will build html-content. For example, here is some line from file:

'title\n'

Now I do:

thatLine.replace('\n', '<br />')
print thatLine

And I still see the text with newline after it.

thatLine = thatLine.replace('\n', '<br />')

str.replace() returns a copy of the string, it doesn't modify the string you pass in.

Just for kicks, you could also do

mytext = "<br />".join(mytext.split("\n"))

to replace all newlines in a string with <br />.

For some reason using python3 I had to escape the "\"-sign

somestring.replace('\\n', '')

Hope this helps someone else!

To handle many newline delimiters, including character combinations like \r\n, use splitlines (see this related post) use the following:

'<br />'.join(thatLine.splitlines())
