jinja2 how to remove trailing newline

In Jinja2, removing trailing newlines from a rendered template can be achieved by using the rstrip filter. This filter removes any whitespace characters, including newlines, from the end of a string. Here's how you can use it:

Assuming you have a Jinja2 template like this:

Hello, World {% if condition %} This is a conditional line. {% endif %}

You can remove trailing newlines by using the rstrip filter when rendering the template:

from jinja2 import Template template_string = """ Hello, World {% if condition %} This is a conditional line. {% endif %} """ template = Template(template_string) context = { 'condition': True } rendered_template = template.render(context).rstrip() print(rendered_template)

In this example, the rstrip() function is called on the rendered template to remove any trailing newlines. The result will be:

Hello, World This is a conditional line.

The rstrip filter is particularly useful when you want to remove any unwanted whitespace, including trailing newlines, from the output of a Jinja2 template.
