Hi,

Regarding the algorithm part of Pairwise Sequence Alignment, I can use
Dynamic Programming (Smith Waterman for local and Needleman Wunsch for
Global Alignment). Please suggest if I should go for dynamic programming.

Also, the above discussion points out that the implementation should be
purely python based for cross-platform compatibility.
