For Windows we provide click-and-run installers. Most Linux distributions will include an optional Biopython package (although this may be out of date). Otherwise you typically download and uncompress the archive, and install from source. See our downloads page for details including the prerequisites.
You can check your installation has worked at the python prompt:
If that gives no error, you should be done. If you get something like “ImportError: No module named Bio” something has gone wrong. Note the case is important.
The Biopython Tutorial and Cookbook (HTML, PDF) contains the bulk of our documentation. See Documentation for more links.
Try executing this in python:
You should get the following output:
This was a very quick demonstration of Biopython’s Seq (sequence) object and some of its methods.
Use the SeqIO module for reading or writing sequences as SeqRecord objects. For multiple sequence alignment files, you can alternatively use the AlignIO module.
