newbie-question about a list

[bobueland at yahoo.com]

I've seen this construct in a script

>>> [x.capitalize() for x in ['a','b', 'c']]
['A', 'B', 'C']

I tried another myself

>>> [x+1 for x in [1,2,3]]
[2, 3, 4]
>>>

Apparently you can do
[function(x) for x in list]

I tried to find a description of this in "Library Reference" but
couldn't find it. Could somebody direct me where this type of construct
is described.
