def information():

my_bucket = get_bucket()

my_text = Response(file_obj.get()['Body'].read(), mimetype='text/plain',)
return render_template('html_with_modal.html', my_text=my_text)

Answer 1

You need to do something like this.
Firstly, save your response in a variable, like
my_text = Response(file_obj.get()['Body'].read(), mimetype='text/plain',)
then you need to render your template and pass your text in as an argument, like
return render_template('html_with_modal.html', my_text=my_text)
and then just like you wherever you want to place my_text in your template, you can put something like
<div class="modal-body" open="{{ url_for('information') }}" method="POST" >
{{my_text}}
</div>
