A bit more complex than necessary... The canonical solution is
funcs = [lambda x, i=i: x+i for i in xrange(10)]

How about:
>>> def make_adder(i):
def adder(x):
return x+i
return adder

hi all,
I need to create a Python list of lambda-funcs that are dependent on
the number of the ones, for example
F = []
for i in xrange(N):
F.append(lambda x: x + i)
however, the example don't work - since i in end is N-1 it yields x+
(N-1) for any func.
So what's the best way to make it val
