comprehension

Python's equivalent of what I want is:

>>> #C#: Dictionary<int, string> tempDict = ...
>>> tempDict = {i : str(i) for i in range(200000)}
>>> tempDict[5]
'5'
>>>

The example is a bit simplified, but I can modify it myself; do not want to bother you with details of proprietary classes.
