Biopython can read and write to a number of common sequence formats like FASTA and FASTQ (developed at the Wellcome Trust Sanger Institute to bundle a FASTA formatted sequence), and when reading files, descriptive information in the file is used to populate the members of Biopython classes, such as SeqRecord.
The Biopython project is an open-source collection of non-commercial Python tools for computational biology and bioinformatics, created by an international association of developers. Biopython can read and write to a number of common sequence formats, including FASTA, FASTQ, GenBank, Clustal, PHYLIP and . It was originally developed at the Wellcome Trust Sanger Institute to bundle a FASTA formatted sequence and its quality data, but has recently become the de facto standard for storing the output of high-throughput sequencing instruments such as the Illumina Genome Analyzer. When reading files, descriptive information in the file is used to populate the members of Biopython classes, such as SeqRecord.
