Does your show() do operations on the input other than "for item in
inputlist"?
I replaced the meat of your loop with
print "X=", X
print "k=", zip(A,X)
print "ik=", izip(A,X)
and this was the output of the first iteration:
X= ('a', 'b', 'a')
k= [(1, 'a'), (2, 'b'), (3, 'a')]
ik= <itertools.izip object at 0x2c6288>

I was under the impression that izip is a better alternative than zip
when the two sets are large.
But thats not what its turning out to be.
(in practice I would have A to be a set of size ~200-300 and B would be
of size ~10-50 )
A = [1,2,3]
B = ["a","b"]
from itertools import product
from itertools import izip
for X in product(B,repeat = len (A)):
k = izip(A,X)
show(k)
[THE ABOVE izip VERSION DOESN'T WORK!]
VS
A = [1,2,3]
B = ["a","b"]
from itertools import product
for X in product(B,repeat = len (A)):
k = zip(A,X)
show(k)
[THE ABOVE zip VERSION WORKS]
Can someone help?
