parse-genbank.py issue

[fconstancias]

Hello,

I am trying to extract 16S operon from a genbank flat files using your script but I got the following error.
(python27)./parse-genbank.py GCF_903181445.1_NZ_Bacteroides_fragilis_8E3_BL_hyb_genomic.gbff

Traceback (most recent call last):
File "./parse-genbank.py", line 7, in
genome=SeqIO.read(sys.argv[1], 'genbank')
File "/Users/fconstan/miniconda3/envs/python27/lib/python2.7/site-packages/Bio/SeqIO/init.py", line 754, in read
raise ValueError("More than one record found in handle")
ValueError: More than one record found in handle

Any help will be very much appreciated.
