Python Flask, how to set content type

Question

I am using Flask and I return an XML file from a get request. How do I set the content type to xml ?

e.g.

@app.route(\'/ajax_ddl\')
def ajax_ddl():

I like and upvoted @Simon Sapin's answer. I ended up taking a slightly different tack, however, and created my own decorator:

from flask import Response
from functools import wraps

def returns_xml(f):
    @wraps(f)
    def decorated_function(*args, **kwargs):
        r = f(*args, **kwargs)
        return Response(r, content_type='text/xml; charset=utf-8')
    return decorated_function

and use it thus:

@app.route('/ajax_ddl')
@returns_xml
def ajax_ddl():
    xml = 'foo'
    return xml

I think this is slightly more comfortable.
