Hi will these be possible?
<tal:b tal:define='dictionary python: {"value1": ["one", "two", "three"], "value2": "two", "value3": "three"}'> <tal:b tal:replace='python: dictionary["value1"][5] | "Value not available"' /> </tal:b>
Obviously these is an incorrect tal expression (the replace one) but there are any way to create an expression like these and correct?
Please look at the Python Dictionary API, especially the has_key() or get() method.

Hi Andreas (Good morning!) Thank you for your light speed response ;) The get() method would be fantastic but my problem is with the list I know that value1 exists in the dictionary but I don't know the length of the list It would be perfect if I have some get method (with default value like dictionary's get) for the list
Another possibility will be some if sentence like expresion ? result for true : result for false Has python these kind of if?
Any idea?
Put the tal:replace-part in a python script, Parameters mdict, mkey idx, msg: try: return mdict.get(mkey,[])[idx] except IndexError: return msg Untested! HTH, Wolfram
