Version Compatibility

Reference examples tested with: BioPython 1.83+

Before using code patterns, verify installed versions match. If versions differ:

• Python: pip show <package> then help(module.function) to check signatures

If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying.

Pairwise Sequence Alignment

"Align two sequences" → Compute an optimal alignment between a pair of sequences using dynamic programming.

• Python: PairwiseAligner() (BioPython Bio.Align)
• CLI: needle (global) or water (local) from EMBOSS
• R: pairwiseAlignment() (Biostrings)

Align two sequences using dynamic programming algorithms (Needleman-Wunsch for global, Smith-Waterman for local).
