pair lists to create tuples in order

Question

I\'d like to combine two lists. If I have the following two lists: {a,b,c,d} and {1,2,3,4} what do I need to do so that I get {{a,1}, {b,2},

Answer 1

An esoteric method is Flatten, which (from the Help Section on Flatten) also allows Transpose of a 'ragged' array.

Flatten[ {{a, b, c, d}, {1, 2, 3, 4, 5}}, {{2}, {1}}]

Out[6]= {{a, 1}, {b, 2}, {c, 3}, {d, 4}, {5}}
