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.

Seq Objects

Create and manipulate biological sequence objects using Biopython.

"Create a sequence object" → Wrap a raw string in a typed sequence container for biological operations.

• Immutable: Seq('ATGC') (BioPython) — string-like, supports complement/translate
• Mutable: MutableSeq('ATGC') (BioPython) — supports in-place edits
• Annotated: SeqRecord(Seq(...), id=...) (BioPython) — adds metadata for file I/O
