Unable to lookup keys in dictionary

[Andreas Tawn]

>I am trying to run p4python API on top of python 2.5.2 and am
extracting a dictionary from perforce. The following code returns the

It looks like you're getting a list with the dictionary as the only
element.

Try...

s = info[0]['serverVersion']
