This shows how valuable it is to post your expected results with your code.

The way most experienced python programmers might do this is with list 
comprehension:

res = [[1, i] for i in xrange(1,7)]

For newer programmers, this might make more sense:

res = []
for i in xrange(1,7):
   res.append([1,i])
