|I need to use a lambda expression
Lambda expressions are a convenience, not a necessity. When having a
problem, it sometimes helps to revert to the unabbreviated def statement.

Good idea. I will try it. I also figured out a way to architecture my
program differently to avoid this problem. But this idiom might be
handy in certain
An idea, i don't know if it will work in your case.
for x in xrange(10):
funcs.append(lambda p,z=x: testfunc(z+2,p))

I need to use a lambda expression to bind some extra contextual data
(should be constant after it's computed) to a call to a function. I had
originally thought I could use something like this demo (but useless) code:
funcs=[]
def testfunc(a,b):
print "%d, %d" % (a,b)
for x in xrange(10):

Assuming b is a dict, it is roughly equivalent to the following (except
that the variables beginning wit

The equivalent of :
def oh_my_yet_another_function_name_why_not_use_lambda(x):
b.setdefault(x,[])
map(oh_my_yet_an
what does the following code mean? It is said to be used in the
calculation of the overlaid area size between two polygons.
map(lambda x:b.setdefault(x,[]),a)
Thanks!
