Displaying item in python dictionary in HTML on new line

Question

I have a python dictionary which stores the HTML title and comments from the user. I want to display each comment on a new line. I'm wondering is there a way to do this through some sort of loop like a while or for? I am displaying it manually for now. I am using flask if that helps. Here is my code:

Python:

with open ("comments.txt", "r") as myfile:
            data=myfile.read()
display_information = {
            'title':'My title'
            'messages':data.split('*')
}
    return render_template('test.html', pageinfo=display_information)

HTML:

{{ pageinfo.messages[0] }}
<br>        
{{ pageinfo.messages[1] }}
<br>
{{ pageinfo.messages[2] }}

Is there a fast way of displaying the messages on a new line?

Iterate pageinfo.messages:

{% for msg in pageinfo.messages %}
    {{ msg }}<br>
{% endfor %}

Cool i'll accept this answer in a minute. Would you know of any way in which if the user wanted to edit the comment, it would then be updated in the text file too? Struggling to find some info.

@fathertodumptious, I don't get your question in the comment. Could you post it as a separate question?

It seems I can only post every 90 minutes so I will leave another comment here when it is posted.
