bpy18. Posting IDs in a NCBI EUtil using Biopython

We can use the keyword parameter usehistory=’y’ to Bio.Entrez.esearch.

We searched for mitochondria review articles, that have free full text available, from years 2012 through 2014.

Because of the additional parameter, two new keywords were returned and we can use in a subsequent eUtil. We print the title of a few records, from the 1223 that were returned.

Entrez.email = "[email protected]"
term = ('"mitochondria"[MeSH Terms] OR "mitochondria"[All Fields])'

' ("2012/01/01"[PDAT] : "2014/12/31"[PDAT]))')
handle = Entrez.esearch("pubmed", retmax = 1500, term = term,
usehistory = 'y' )

values = Entrez.read(handle)
print("QueryKey:", values['QueryKey'])
print("len(WebEnv):", len(values['WebEnv']))

summary = Entrez.esummary(db="pubmed", retmax=values['Count'],
