[Tutor] string to list

[Huy Ton That]

Speaking of which, is there some place you or anyone can recommend on
picking up all the constructs for list comprehension & generator
comprehension. I've perused the python.org documents and have just been
building them according to example.

How can I pick up more advanced usage?

I mostly catch myself using it to return a list of functions like:

>>> class foo(object):
...     def __init__(self, bar):
...             self.bar = bar
...
>>> [(foo(i)) for i in range(0,10)]
[<__main__.foo object at 0x00C54FD0>, <__main__.foo object at 0x00C54FF0>,
<__ma
in__.foo object at 0x00C54F50>, <__main__.foo object at 0x00C54F30>,
<__main__.f
oo object at 0x00C59050>, <__main__.foo object at 0x00C59070>, <__main__.foo
obj
ect at 0x00C590B0>, <__main__.foo object at 0x00C590D0>, <__main__.foo
object at
 0x00C59110>, <__main__.foo object at 0x00C59130>]
