How To Add Suffix To A Plain Text In Python

I have the following text that I want to send by mail. I have to convert it to html, therefore to each line separator I have to add . How can I do it in such a way that it fits me?

Solution 1:

You're probably looking to replace newlines

>>> text = """
... Hi, my name is John,
... Regards
... """>>> import re
>>> print(re.sub(r"\n", "<br>\n", text))
<br>
Hi, my name is John,<br>
Regards<br>

Alternatively, you can use <pre> (preformatted text) to write out the text as-is! (though it's really more for code blocks and probably not appropriate for other text)

<pre>
Hi, my name is John,
Regards
</pre>

As PacketLoss notes, if you only have a trivial character/substring to replace, using the .replace() method of strings is fine and may be better/clearer!

Solution 2:

If you want to replace all new lines \n with <br> you can simply use string.replace()

print(text.replace('\n', '<br>'))
#<br>Hi, my name is John,<br>Regards<br>

To keep the new lines, just modify your replacement value.

print(text.replace('\n', '<br>\n'))
<br>
Hi, my name is John,<br>
Regards<br>
