python & ipxe - syntax errors

[singularity42]

I am setting up a new infrastructure. Previous one used mod_python with the following script to handle some python work and then pass it to ipxe. On the new setup I am using mod_wsgi and I can not seem to get it to work.

Code:

<%
import requests, json, cgi

req.headers_out['Content-Type'] = 'text/plain'
req.content_type = req.headers_out['Content-Type']

ip = ""
default = ""
build = False

mac = cgi.parse_qs(req.args)["mac"][0]

r = requests.get('http://puppetnext.lab.beer.town/api/v2/hosts?search=has_mac=' + mac, auth=('user', 'password'), verify=False)
resultjson = r.json()["results"]
if len(resultjson) > 0:
        hostid = resultjson[0]["id"]

        hostr = requests.get('http://puppetnext.lab.beer.town/api/v2/hosts/' + str(hostid), auth=('user', 'password'), verify=False)
        ip = hostr.json()["ip"]
        build = hostr.json()["build"]

if ip:
        if build:
                default = "build"
        else:
                default = "local"
else:
        default = "discovery"

%>#!ipxe

menu Boot options for <% req.write(mac)%>
item --key l local              Continue with local boot
item --key d discovery          Boot foreman discovery image
item --key b build              Build local host <% req.write(ip)%>
choose --default <% req.write(default)%> --timeout 5000 target && goto ${target}

Before, this would execute the python script and then set the correct settings for the following ipxe script. Now I just seem to get python syntax errors.

Any idea whats going on here?
If I access it via boot.py:

Code:

If I access it via just boot:
