Hi Martin!
Thanks! I think last time you mentioned that IP
already had generators--were you referring to 0.9.2 or
some other version in the future?
Also... regarding the Array, is there any workaround?
I tried this:
from System import Array, Convert, Int32
pyList = [9, 7, 8, 4, 6, 3, 6, 8, 4, 1]

"generators" != "generator expressions"
the former is an execution mechanism which lets a function or method
incrementally "yield"
Hi Ray,
Fredrik already asnwered your generator expression related question. As
for the arrays,
Here is solution that seems to work:
>>> from System import *
>>> a = Array.CreateInstance(Int32, 10)
>>> a
System.Int32[](0, 0, 0, 0, 0, 0, 0, 0, 0, 0)
>>> r = range(10)
>>> for i in r: a[i] = i
>>> a
Hi Martin,
Thanks, you spotted the source of the problem. When I
removed GetType() from around Int32, my solution
works:
from System import Array, Convert, Int32
pyList = [9, 7, 8, 4, 6, 3, 6, 8, 4, 1]
toBeSorted = Array.CreateInstance(Int32, len(pyList))
for index, item in enumerate(pyList):
Thanks for the clarification, Fredrik!
Cheers,
Ray
"generators" != "generator expressions"
the former is an execution mechanism which lets a
function or method incrementally "yield" a sequence of
values, instead of returning a single value
(introduced in Python 2.2); the latter is syntactic
suga
I must have mistyped the GetType function the first time around
because IronPython would find it otherwise.
The IronPython's logic to look-up built-in methods finds the method
GetType on the __builtin__ class implementation.
I don't have solution for this yet, but at least we understand what
is g
All the fun Linq bits run on beta 2. All that's needed is a way to make use of
extension method attributes, which is remarkably Pythonic: foo.Bar(baz) ->
Gleep.Bar(foo, baz). Python already has lambdas, but could use a means to
generate expression trees rather than functions.
