检测Python / Django textarea字段内的换行符

Question

I have a textarea field in Django from which I want to detect line breaks. I can see that the line breaks are stored as reloading the page with the user input shows the breaks that the user inputted, but I can't detect them in Django/Python.

When I look at the output from PostgreSQL I can see \\r characters, but these don't seem to show up within the Python environment.

I'd like to do something like this:

text_blocks = text_area.split("\r")

But this doesn't work and I suspect is naive.

How can I detect these seemingly invisible line breaks within Python/Django?

Answer 1

Try splitlines() , this is a built-in string method of python:

text_blocks = text_area.splitlines()

From the docs :

Return a list of the lines in the string, breaking at line boundaries. Line breaks are not included in the resulting list unless keepends is given and true.
