Biopython include a GenBank parser which supports GenPept. The parser is in Bio.GenBank and uses the same style as the Biopython FASTA parser. You need to create the parser first then use the parser to parse the opened input file. 4.2.3 SeqRecord objects from GenBank files¶. As in the previous example, we’re going to look at the whole sequence for Yersinia pestis biovar Microtus str. 91001 plasmid pPCP1, originally downloaded from the NCBI, but this time as a GenBank file. Again, this file is included with the Biopython unit tests under the GenBank folder, or online NC_005816.gb from our website. Biopython API documentation: Bio.GenBank ; Iterator Iterate through a file of GenBank entries Dictionary Access a GenBank file using a dictionary interface. ErrorFeatureParser Catch errors caused during parsing. index_file Get a GenBank file ready to be used as a Dictionary. search_for Do a query against GenBank. download_many Download As of now, the latest version is biopython-1.72. Download the file and unpack the compressed archive file, move into the source code folder and type the below command − Step 8 − Copy the sample GenBank file, ls_orchid.gbk provided by BioPython team https: We’re going to draw a whole genome from a SeqRecord object read in from a GenBank file (see Chapter 5). This example uses the pPCP1 plasmid from Yersinia pestis biovar Microtus, the file is included with the Biopython unit tests under the GenBank folder, or online NC_005816.gb from our website. Now we use these GIs to download the GenBank records - note that with older versions of Biopython you had to supply a comma separated list of GI numbers to Entrez, as of Biopython 1.59 you can pass a list and this is converted for you:
@zach I have done quite some work with this type of data on MATLAB as well as Python, feel free to ask if you have similar questions :) – hello_there_andy Nov 26 '13 at 17:01
That was pretty easy because GenBank files are annotated in a standardised way. a network connection, to download and parse sequences from the internet. Note that just because you can download sequence data and parse it into a SeqRecord object in one go doesn’t mean this is Database indexed files¶ Biopython 1.57 introduced an Biopython can read and write to a number of common sequence formats, including FASTA, FASTQ, GenBank, Clustal, PHYLIP and NEXUS. When reading files, descriptive information in the file is used to populate the members of Biopython classes, such as SeqRecord. This allows records of one file format to be converted into others. I'm sure we have/had an issue on this, but right now I can't find it. Certainly I remember investigating a similar report. This is a malformed GenBank file (as per all the Biopython warnings), it looks like bits of the location are missing with extra comma's remaining. I would expect SeqIO.read to be able to parse a Genbank file with the value

urllib() is a module that lets Python download files from the internet with the .urlretrieve method. > GenBank) and to some common locally installed software (ie.
Make sure complete record is selected, and then choose destination of File. Download options will come, and download the Genbank file. Rename the file to BC135714.1.gb and save it to the working directory or a subfolder, such as data, under the working directory. In this program, the function Bio.SeqIO.read is used to parse the text file.

This is used in parsing GenBank and EMBL files where the sequence may not be present (e.g. for a contig record) and when parsing QUAL files (which don't have the sequence) GenomeDiagram by Leighton Pritchard has been integrated into Biopython as the Bio.Graphics.GenomeDiagram module If you use this code, please cite the publication Pritchard et
