IronPython almost has full Python 2.4 compliance, so it is not very 
different from Python at all.

In addition 'translating' MSDN docs for use with IronPython is quite easy.

At ResolverSystems we are building a full desktop application using 
IronPython and encountering very few difficulties. The only .NET 
functionality we have found that isn't exposed to IronPython (for which 
we have had to use C#) are a few parts needed for our functional tests. 
Only our program launcher uses C# in our production code.

This means you should find it easy to interface .NET code to IronPython. 
There are possibly some limitations that I haven't yet found. For 
example, I believe it is not yet possible to compile Python scripts.

If you have specific Python questions then comp.lang.python is a good 
place to ask :

http://groups.google.com/group/comp.lang.python?hl=en

For a good introduction to Python, the following online book is often 
recommended :

http://diveintopython.org/

For IronPython questions and Python-.NET interaction questions, this is 
a good forum to ask.

Hopefully in the next few days I will do a brief tutorial on using 
Windows Forms with IronPython. It will only show the basics, but that 
ought to be enough to show how to read the MSDN docs from a Python 
perspective.

All the best,

Fuzzyman

[IronPython] Learning IronPython?

[Lesley & Mitch Barnett]

Hello,

 

I am sure this question has been answered before, but I can’t
find the answer...  I am a C# programmer and have been using MS technologies
since 1991.

 

However, I know little about IronPython.  Can anyone suggest
any books or reading material to get me up to speed ASAP?  Is there anything
special about IronPython that is different than Python?

 

I have downloaded the latest IronPython Beta and went
through the tutorial and have also been through the April VSSDK examples to a
certain degree.

 

Sorry if this is a repeat question.

 

Regards,

 

Mitch

Re: [IronPython] from xml import xpath

[Greg Lee]

I looked at the .c 
for the likely PYD, and it's not playing tricks with the paths---I think the 
problem is simply IP's not supporting PYD format. 
 
If IP can't import 
from PYD format, perhaps it could throw an exception that identifies 
the offending pyd rather than just identifying the original import 
statement, which in this case is five levels up.  That's the only 
improvement in user experience that's warranted.
Writing an xpath wrapper around 
System.Xml.Xpath is not a good use of anyone's time now and probably a dead-end in the 
long-term.

You’re right, I did

It would seem that you may be right about the Pyd’s (it at least requires a 
C compiler, making that likely – and almost guaranteeing it won’t work w/ 
IronPython).
 
Unfortunately we 
don’t support PYD’s currently (and aren’t likely to soon) so most likely 
this won’t currently work. If you absolutely need XPath support in the mean 
time I’d suggest using .NET’s XMLPath (and if you need to work on both you 
could make a thin wrapper over either PyXml for CPython and .NET’s XPath 
support).  For example:
 
import 
clr
clr.AddReference(‘System.Xml’)
import 
System.Xml.XPath as XPath
 
xpathDoc = 
XPath.XPathDocument(‘file://foo.txt’)

They don't do the same
thing..
fragment 1 iterates over a *copy* of the dictionarys keys, while fragment 2
iterates over the dictionary

Re: [IronPython] IronPython on the Compact .NET Framework

[Haibo Luo]

Currently .NET compact framework does not support DynamicMethod (among other 
features), which is widely used in current IronPython implementation.

We will contact .NET CF team for this feature request.

Thanks!

Hello all,

I realise this has been discussed on the mailing list several times before.

Just to add that I (as an individual) and the company I work for
(ResolverSystems) would be very interested in seeing IronPython for the
.NET compact framework, were that to become possible. :-)

Any word on Beta 7 by the way ?

All the best,

Subject: [IronPython] default contructor allows parameters

Hi all,

It seems that IronPython is allowing parameters to the default
constructor but CPython isn't.


CPython

 >>> class Foo(object):
... pass
...
 >>> Foo(5)
Traceback (most recent call last):
  File "", line 1, in ?
TypeError: default __new__ takes no parameters
 >>>

IronPython Beta 6

 >>> class Foo(object):
... pass
...
 >>> Foo(5)

 >>>
