Hi,
I'm using the json module to create a JSON string, then

import json
data = [ { y:55.11, color:colors[0], drilldown:{name: 'MSIE

9.0'],data: [10.85, 7.35, 33.06, 2.81],color: colors[0] }} ]
data_string = json.dumps(data)
Many thanks for any suggestions on how to do this.
Just quote them: data = [ { 'y':55.11, 'color':colors[0],
'drilldown':{'name': 'MSIE versions','categories': ['MSIE 6.0',
'MSIE 7.0', 'MSIE 8.0', 'MSIE 9.0'],'data': [10.85, 7.35, 33.06,
2.81],'color': colors[0] }} ] Incidentally, dictionary keys in
Python don't have to be strings, but merely 'hashable', which
includes integers, floats and tuples amongst others.
Thanks for your reply, but the javascript function expects option

Both Python source code and JSON require the dictionary keys to be
quoted, so using the json module to generate JavaScript code isn't
going to give you what you want.
It shouldn't be too difficult to write a simple function to do it,
considering the limited range of types.
