biopython

Provides Biopython (Bio.Seq, Bio.SeqIO, Bio.Align, Bio.Entrez, Bio.Blast, Bio.PDB, Bio.Phylo, Bio.motifs, Bio.SeqUtils, Bio.Restriction) for sequence handling, file parsing, NCBI access, BLAST, structures, and phylogenetic trees in Python. Reads, writes, and converts FASTA, GenBank, FASTQ, PDB, mmCIF, Newick, and NEXUS files. Use when manipulating or translating DNA, RNA, or protein sequences, converting sequence file formats, fetching records from NCBI via Entrez, running or parsing BLAST searches, doing pairwise or multiple sequence alignment, analyzing PDB structures, or building and editing phylogenetic trees. For quick lookups use gget; for multi-service integration use bioservices.

Compatibility

Requires Python 3.10+, NumPy, and Biopython. Entrez and web BLAST examples require network access; local BLAST/MUSCLE examples require those command-line tools installed separately.
