Any suggestions for transforming the sequence: [1, 2, 3, 4...] Where 1,2,3.. are it the ith item in an arbitrary sequence into a succession of tuples: [(1, 2), (3, 4)...] In other words, given a seq and an integer that specifies the size of tuple to return, then for example: seq = [a,b,c,d,e,f] for e in transform (seq, 2): print e would return (a,b) (c,d) (e,f)
