Hi Troels, You have to be very careful with Python 3 compatibility when using lambda. I actually actively avoid this construct, as it may be removed in the future. If you would like to use it, make sure you thoroughly test it with Python 3. Note this very important post by the inventor and lead developer of Python:
http://www.artima.com/weblogs/viewpost.jsp?thread=98196 >From this, the lambda construct appears to be in danger of deletion in future Python versions. Guido doesn't like it, so he may just decide to kill it one day. Therefore it might be better to avoid it.
