I was able to write a python script to check an edx problem between tags. However I would like to include a python function from a file, in order to reuse the code in several problems. I tried the following code:
<problem>
<script type="loncapa/python" src="/static/textinput.py" />
<customresponse cfn="check_function">
<script type="loncapa/python">
<![CDATA[
import json
def check_function(e, ans):
# ... my code ...
</script>
<jsinput
gradefn="getGrade"
get_statefn="getState"
set_statefn="setState"
initial_state='{"selectedChoice": "[]"}'
width="600"
html_file="/static/Ex1_3 v2.html"
title="Problem"
sop="false"/>
</customresponse>
</problem>
I get the following error when saving the problem:
Problem block-v1:Casal+Basic1+1701+type@problem+block@55479f8087e64d2395b730037cbe83c3 has an error: cannot create LoncapaProblem block-v1:Casal+Basic1+1701+type@problem+block@55479f8087e64d2395b730037cbe83c3: 'NoneType' object has no attribute 'replace'

data = data.replace("<", "<")
Is it possible to do this? If so, is it correct to use the tag:? Of course the file textinput.py is uploaded and works well in python.
<script type="loncapa/python" src="/static/textinput.py" />
