How to List NCBI Databases with Bio.Entrez.einfo() function?

Bio.Entrez.einfo() function allows you to list NCBI Databases and their related information. It uses the Entrez Web services provided by www.ncbi.nlm.nih.gov.

1. Get a list of NCBI databases.

fyicenter$ python 
>>> from Bio import Entrez
>>> Entrez.email = "A.N.Other@example.com"

>>> handle = Entrez.einfo()
>>> result = Entrez.read(handle)
>>> handle.close()

>>> print(result)
{'DbList': ['pubmed', 'protein', 'nuccore', 'ipg', 'nucleotide', 
 'structure', 'genome', 'annotinfo', 'assembly', 'bioproject', 
 'biosample', 'blastdbinfo', 'books', 'cdd', 'clinvar', 'gap', 
 'gapplus', 'grasp', 'dbvar', 'gene', 'gds', 'geoprofiles', 
 'homologene', 'medgen', 'mesh', 'nlmcatalog', 'omim', 'orgtrack', 
 'pmc', 'popset', 'proteinclusters', 'pcassay', 'protfam', 'pccompound', 
 'pcsubstance', 'seqannot', 'snp', 'sra', 'taxonomy', 'biocollections', 
 'gtr']}

2. Get more information on the "pubmed" database.

>>> handle = Entrez.einfo(db="pubmed")
>>> result = Entrez.read(handle)
>>> handle.close()

>>> result["DbInfo"]["Description"]
'PubMed bibliographic record'

>>> result["DbInfo"]["Count"]
'35230792'

>>> result["DbInfo"]["LastUpdate"]
'2023/01/31 23:59'

>>> result.keys()
dict_keys(['DbInfo'])

>>> result['DbInfo'].keys()
>>> result['DbInfo'].keys()
dict_keys(['DbName', 'MenuName', 'Description', 'DbBuild', 'Count', 
  'LastUpdate', 'FieldList', 'LinkList'])
