Version Compatibility

Reference examples tested with: BioPython 1.83+

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

• Python: pip show biopython 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.

Read Sequences

Read biological sequence data from files using Biopython's Bio.SeqIO module.

"Read sequences from a file" → Parse file into a collection of SeqRecord objects with IDs, sequences, and annotations accessible.

• Python: SeqIO.parse() or SeqIO.read() (BioPython)
• R: readDNAStringSet() or readAAStringSet() (Biostrings)
