A question about making a sort-of-counter.

[Justin Park]

Suppose I have a list.
a = list()
And suppose allowed digits as the element are 1,2,3,4,5.

What can I do in order to iterate over all possible values for each element?
For instance, the sequence of the list I want to have would be
[1,1,1,1,1]
[1,1,1,1,2]
[1,1,1,1,3]

.....

[5,5,5,5,4]
[5,5,5,5,5]

How can I make it happen?

Thanks,
Justin.

from itertools import product

for item in product([1, 2], repeat=2):
print item
